Two couples on a tropical vacation consider a foursome as a means of spicing up their sex lives in this lighthearted comedy penned by popular Czech author Michal Viewegh. Ondra (Hynek Cermák) and Vitek (Jirí Langmajer) have been housemates and colleagues for years. They get along like brothers, their wives enjoy a close friendship, and their children have all grown up together. But now, as Ondra and Vitek approach middle age, a frank discussion about their sex lives yields some troubling results. Both men love their wives, but neither can remember the last time they experienced true passion in the bedroom. As the two couples embark on a trip to the Caribbean, the restless husbands' eyes wander to their best friend's wives. Could a bit of spouse swapping put the spark back in their love lives?
