Plan B (2009)

Bruno is dumped by his girlfriend; behind a calm, indifferent expression, his mind plans a cold, sweet vengeance. She, a modern girl, keeps on seeing him once in a while, but has another boyfriend, Pablo. Bruno becomes Pablo's friend, with the idea of eroding the couple, maybe introducing him to another woman. But, along the way, the possibility of a plan B arises, a more effective one, which will put his own sexuality into question.
