Elia Domenzaín

Four lonely and disenfranchised urbanites in contemporary Mexico City: a preteen boy under tremendous emotional strain, the pretty cashier with whom he is infatuated, an enraged and embittered cabbie, and the estranged daughter of one of his fares. Per the film's title, these characters pair off, finding unexpected hope and salvation in one another.

After an all-nighter, Ricardo gets to his apartment only to find his family ready to have an intervention for him. His struggle with addiction is the least of his problems in this peculiar event where he faces his drug dealer, a prostitute and the worst company of all: his family.
