At a convenience store early in the morning, Juan (Gastón Pauls), a con artist, successfully scams one cashier, but he is caught when he attempts the same scam on a different cashier at the same store. Marcos (Ricardo Darín), who has been observing Juan, pretends to be a police officer and takes Juan away. Once they are far enough from the store, Marcos reveals he is a fellow con man whose partner has recently disappeared. He asks Juan to try out being his partner for the day, an arrangement to which Juan agrees because his father, who is also a con man, is in jail and needs to raise $70,000 quickly in order to bribe a judge.
