Today is the day Isa has decided to tell Tomás, her best friend, that she's in love with him. They've lived together for years, and she's finally ready. But today is also the day Tomás has chosen to tell Isa that he's planning to move in with his girlfriend, Vanesa. Isa is a hopelessly romantic independent actress who experiences life through fiction. Tomás, on the other hand, is pragmatic and determined to get his life on track. Between them unfolds a game of cat and mouse, where it's never quite clear who's chasing whom. The only question is: who will dare to be honest first?
