The Rover follows a group of characters, brought together by their connections to four banished Cavaliers from England. Due to the play occuring during Carnival in Naples, Italy, society is relaxed, less strict, and the common use of masks and disguises allows the characters to move and interact with each other in less-inhibited ways.
The play begins with sisters Florinda and Hellena discussing love. Hellena, who is supposed to take her religious vows and join a nunnery once Lent begins, teases and begs her sister to tell her what love feels like. Florinda demures, but eventually it is revealed that she is in love with Colonel Belvile, an English soldier who defended her during a siege at Pamplona. However, they are soon joined by their brother, Don Pedro, who pushes Florinda to think fondly on Don Vincentio (who her father wants her to marry), or, if not on him, to put her affections on Don Antonio. Antonio and Pedro are friends, and Antonio is also wealthy and powerful. Hellena scorns Don Vincentio, and Pedro for condemning his sister to marry an old man, and Pedro responds by reminding Hellena that she is destined to be a nun. He then tells Callis, the girls’ governess, to keep them inside and not let them roam the streets, and goes out to enjoy Carnival. His orders are in vain, for Cousin Valeria arrives with costumes, and the girls go to dress and enjoy their Carnival freedom.
We next meet Belvile, Frederick, and Ned Blunt – three English cavaliers who are trying to enjoy their time in Naples. Belvile is glum, because he loves Florinda but her brother has barred him from the house. They are soon met by Willmore, their friend and a naval captain who has just arrived in Naples. They flirt with some passing women and snipe at each other, and soon, Florinda, Hellena, and Valeria arrive on the scene, masked and disguised as gypsies. Hellena and Willmore flirt, and Willmore is very taken by her wit and bold words. She promises to meet him later. Florinda and Belvile speak, but he does not initially realize who she is and is cold, as he is determined to be faithful to Florinda. She gives him a letter and flees with her kinswomen when she sees her brother approaching. Belvile recognizes the handwriting and realizes that Florinda is telling him to come carry her off that night to escape her brother. Blunt, who has been speaking to another woman, Lucetta, leaves with her – the other Englishmen laugh over this, hoping that she’ll make a fool of him so they can continue to laugh at him, but they realize he has all their money and hope he won’t be made a fool of too soon. They leave, for other amusements.
Belvile, Willmore, and Frederick are on their way to see what this business of a courtesan selling herself is, and they come upon Blunt again. He is completely taken by Lucetta, and the other men laugh and advise him to not be so in love as they take their money back. They reach the house of Angellica Bianca as her servants are putting up several portraits of her. The Englishmen agree that she is beautiful, but the price of a thousand crowns a month is far too high, so they leave. Don Pedro arrives, sees the price, and goes off to fetch the money – his uncle was Angellica’s former lover, and he had fallen in love with her when she was beyond his reach. Don Antonio is also interested in Angellica, and Pedro overhears his servant reminding him that he is supposed to marry Florinda – but Antonio tells his servant that it doesn’t matter, he can have Angellica and still marry Florinda. Pedro is offended for his sister’s honor, and when Angellica’s servants come out to see who will pay the price and Antonio steps up, Pedro is enraged. They fight, but Willmore and Blunt enter to break them up. Pedro challenges Antonio to a duel the next day, and when Antonio accepts, Pedro leaves. Willmore tries to steal a small portrait of Angellica, but Antonio stops him and they fight, with the other Englishmen joining Willmore and other Spaniards arriving to help Antonio. Soon, the English fight off the Spaniards and Angellica asks Willmore to speak with her inside. The others depart.
Inside, Willmore speaks to Angellica of love and of her vanity of pride, that lets her sell herself to the highest bidder. He tries to convince her to sleep with him for free, and, though she normally would never think of such a thing, she has fallen in love with him for his wit. She agrees and leaves the sitting room with him, much to her servant Moretta’s displeasure.
Florinda, Hellena, and Valeria enter, in different disguises than they wore before. The other two tease Hellena about being in love. Belvile, Frederick, and Blunt enter, but because Willmore is not with them, the women hold back and eavesdrop. Willmore soon emerges from Angellica’s house and brags about enjoying her charms for free. Hellena has overheard, and though she initially pretends she hasn’t when she speaks to Willmore, she soon reveals that she heard everything and, after showing Willmore her face, makes him promise never to see Angellica again. As she is as beautiful as she is witty, he agrees. Unfortunately, Angellica has entered in a mask, and overhears. She is furious that he has betrayed his vows to her. Meanwhile, Florinda and Valeria are testing Belvile’s vows to Florinda, but he stands unmoved and faithful to her. Florinda hands him a jewel as she leaves, and he realizes that it contains her portrait. He resolves to rescue her that night, and Willmore and Frederick agree to help.
We then catch up with Blunt, who has been taken to Lucetta’s house by Sancho. Sancho is posing as her servant, but he is more along the lines of a pimp to her, working with her and Phillippo (Lucetta’s gallant) to trick men out of money and belongings. Lucetta tells Blunt she is going to get undressed and get in bed, and Sancho then brings him in to her once she is ready. He enters in the dark, and while he is making his way to the bed, it descends via a trapdoor. Leaving Blunt to fall down the trap after he has undressed and left all his belongings on the floor. Lucetta, Sancho, and Phillippo enter, laughing over Blunt’s folly and taking joy in all the riches they got off him. They do not return for the rest of the play.
We catch up with Blunt as he crawls out of a sewer, furious at how he’s been tricked. He goes to make his way back to his friends.
We next move back to Florinda, who is in her garden in a state of undress (likely only wearing her chemise). She unlocks the garden gate and goes to wait for Belvile, but, unfortunately, a drunk Willmore enters. He mistakes her for a whore and tries to rape her. As she starts to scream, Belvile and Frederick enter and get between them. Florinda escapes as her brother and servants enter the garden, and the Englishmen flee. The entire event is smoothed over as a servant tells Pedro that Florinda is asleep, and the gate was probably left open by servants out celebrating Carnival. Everyone goes back to bed.
Belvile is furious with Willmore for trying to assault Florinda, and though Willmore defends himself, saying that he didn’t know it was Florinda, Belvile is still angry, saying that was still no reason for Willmore to be “a beast, a brute, a senseless swine?” (3.6, line 2-3). They nearly fight, but Frederick calms them. They have reached Angellica’s house, and Willmore knocks, hoping to satisfy himself there. Willmore and Frederick leave as Antonio arrives. Willmore is upset that Antonio has paid for Angellica, and attacks him. The two men fight in the dark, and others approach – Belvile has heard the fighting and returned to keep Willmore from making trouble. However, once the fighting stops, Willmore stumbles away and Belvile is caught in his place because of the dark. He is taken away as the act ends.
We open on Belville in a cell, locked up. Antonio enters and reveals that he has to fight a duel the next day, but he has been injured by Willmore and cannot fight. He tells Belvile to dress in his clothes and wear a Carnival mask so he can fight in his stead, and in exchange Belvile can go free. He tells Belvile that he is to fight “a rival, sir, about the maid we love,” (4.1, lines 51-52). He does not seem to know who Belvile is, and Belvile isn’t sure who he means, as “the maid” could only mean Florinda (Angellica cannot be called a maid), but Belvile knows that he isn’t the one who challenged Antonio. Nevertheless, he agrees so he can escape imprisonment or death.
Later that day, Florinda and Callis arrive at The Molo in masks, as they have heard from Stephano (Don Pedro’s servant) that her brother is to duel someone, he doesn’t know who, but he knows that it is about Florinda. Naturally, she assumes the other fighter is Belvile. Belvile and Pedro arrive, both in masks. They begin to fight, but Florinda gets in the way, not wanting her brother to get hurt. They try to duel again, but Florinda begs Belvile to stop, “By all you hold most dear, by her you love,”(4.2, line 44). He lays down his sword, and Pedro believes that Antonio has chosen Florinda over Angellica. He gives Florinda to Belvile-as-Antonio, and tells them they should get married now. Florinda is distressed, until Belvile reveals that he is, in fact, her love. However, Willmore and Frederick arrive at that moment and run to embrace Belvile, knocking his mask away. Pedro recognizes Belvile and takes back Florinda. They both leave. Belvile makes to fight Willmore and Frederick gets in between – as they are squabbling, Angellica enters with her entourage.
Angellica is angry as Willmore, for she has discovered that his “little gispy” is in fact Don Pedro’s second sister. Willmore separates from Belvile and goes to speak to her, trying to win her back in spite of her anger towards him. However, Hellena enters, dressed in men’s clothing, and sees Willmore speaking to Angellica. She devises to make him pay for breaking his promise, and speaks to Angellica, telling her of a young lady who had her heart broken by a man who had fallen in love with Angellica. Eventually, Willmore realizes that the boy is indeed Hellena, and snipes at her. However, a page comes in to tell Angellica that Antonio wishes to see her, and Hellena flees, lest she be discovered. Angellica releases Willmore, as she has decided to return to the wealthy men who will pay for her, and he leaves. She is distressed, but goes to see Antonio.
What follows is a series of scenes where people just miss each other and confuse each other due to masks. Florinda and Valeria have escaped the house to go find Belvile. They see Belvile, but he is with Pedro and Wilmore, so the women pass by them separately. Wilmore is interested in Florinda’s figure, and thinks she looks back at him, so he follows her. Valeria follows behind them as Belvile and Pedro continue on. Hellena sees Willmore following a lady, and sends a page to follow him. Florinda realizes she’s being followed, and ducks into a house. She loses Willmore, but Valeria and the page see what house Florinda went in.
We move to inside the house, where Blunt is sitting in his underclothes. He is angry about being tricked, and wishes a woman, any woman, were there so he could take out his revenge on her. As if on cue, Florinda entered, not sure if the house is occupied or empty. She happens upon Blunt, who makes as if to beat and rape her. Frederick enters, seeming sympathetic to Blunt’s desire for revenge, but Florinda offers him a ring to leave her be. Frederick realizes that she might not be a common woman, so manages to separate her from Blunt and goes to lock her in his rooms. Soon, Belvile and Willmore arrive with Pedro, and after making fun of Blunt, Blunt announces that he has a woman locked up, and she gave him a ring. Belvile recognizes the ring as one he gave Florinda, but as Pedro is in the room, he can’t just say that he thinks Florinda is the one locked up. As he is trying to quietly sort it out, Willmore suggests that the man with the longest sword gets the girl first. Don Pedro has a toledo sword, and goes up with Frederick. Florinda soon comes running down, pursued by Pedro, and just as Belvile can’t decide whether to reveal Florinda or not, Valeria runs in, apparently looking for Pedro. She announces that Hellena has fled in the guise of a page, and Pedro must find her. Pedro leaves, and Florinda reveals herself. A Father is sent for, and Florinda and Belvile go to be married, and Frederick and Valeria agree to be married. Willmore is left alone, and Angellica arrives, furious at him for making a fool of her. She has a gun and threatens to shoot him until Antonio arrives and takes the gun from her. He offers to shoot him for her, but she relents, allowing him to live as she goes off with Antonio. Pedro returns, to find out that Antonio is with Angellica now, and that Belvile and Florinda have married. He goes out with Belvile, and Hellena enters, still dressed as a man. She spars with Willmore, and gets him to agree to marry her. The others all return, and Pedro reluctantly gives his permission for Hellena to marry Willmore – he’s tired of guarding her honor.
