A group of friends meet one summer day to celebrate the arrival of one of them who comes from Mexico and who will bring them together again.

In Santiago, Andrés Barros is a partner at an up-and-coming law firm. He's getting married, and his friends, including his law partner Roberto, arrange a bachelor party where he spends the night with a prostitute, Gloria. She later shows up at his office and the passion continues, against his better judgment. Soon, Andrés is entangled in sex, lies, videotape, and blackmail. His relationship with Rosario, his fiancée, is strained, he neglects his work, and there's a dead body in a bathtub. A pimp, a whore, a doorman, a receptionist: where are the decent people?

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.
