A cold,husband has his marriage on the verge of failure. One day he will begin an affair with an eccentric and impulsive woman who will awaken the sensitive and affected man who slept in him. But this new attitude of his will make his wife believe that he is interested in her again, reliving the relationship. Thus, when the situation becomes untenable, the husband must make a difficult decision between moving forward with his recovered marriage or go along with a vertiginous romance that could make him a better person.

Gastón Fernández has arrived at 34 without too much to show or brag about. He has no money, job, girlfriend, friends or life plan. He's a composer that doesn't compose. The one-time "most likely to succeed" at Santiago's Musical Conservatory has passed from promise to failure. He feels he is beginning to wander alone. Isolated and detached. Gastón feels that everyone judges him and see the word loser tattooed on his forehead. At the same time, an alter-ego, a sort of doppelgänger, haunts him.
