A web of romantic entanglements covers a growing circle of friends in this romantic comedy drama from Spain. Tomas (Alex Brendemühl) is a college instructor who has been secretly dating one of his students, Ana (Miranda Makaroff). Making the matter more complicated is the fact that Ana's uncle is Mario (Eduard Fernández), one of Tomas' best friends. Mario has long been involved with Sara (Vicenta N'dongo), but he has reason to believe she is having an affair, and he's desperate to hold on to her. At the same time, Mario has met Cristina, and is trying to fight his interest in her. Irene (Mònica López) and Manu (Chisco Amado) are another seemingly happy couple fighting infidelity when she begins having second thoughts about their relationship. And Andres has fallen for Sofia (María Pujalte), a clerk at his favorite bookstore, but he learns she's still pining for Eric, who talked her into bed one night but has yet to come back to her.
