A man wants to turn his ex against her new lover, but the relationship between these three people takes a detour none of them expected in this comedy-drama from Argentina. Bruno (Manuel Vignau) is a sloppy and lackadaisical guy who has been dating Laura (Mercedes Quintero) for a while. Laura has grown tired of their relationship, and tells Bruno that she wants to date someone else. While Bruno feigns a casual attitude over this news, inside he's crushed, and when it becomes evident that though they may still be friends, Laura has clearly chosen good-looking Pablo (Lucas Ferraro) as her new lover, he sets out to destroy their budding romance. Bruno's scheme is two-fold -- he'll befriend Pablo while spreading rumors about him that are certain to get back to Laura. However, Bruno finds that he gets along with Pablo far better than he expected, so much so that his feelings for him start moving in a direction he never anticipated. Plan B was the first feature film from director Marco Berger.
