In Buenos Aires, the swindler Juan cheats the cashier of a convenience store with a bill-changing scam observed by Marcos. Then Juan tries to lure the cashier on the next shift but he is caught by the manager. Marcos claims to be a police officer and arrests Juan; he also brings the money claiming to be evidence. Sooner Juan learns that Marcos is actually an experienced con artist and he invites Juan to be his partner in a scheme. They head to a five-star hotel where Marcos meets his estranged sister Valeria in the reception. She tells that Marco's friend Sandler is very ill and wants to talk to him in the locker room. Sandler explains that he had forged a sheet of the valuable stamps Nueve Reinas using a picture he took from the collection that belongs to his sister. He also tells that the Spaniard Vidal Gandolfo that is lodged in the hotel is a collector of stamps and will travel on the next morning. Therefore, the stamps should be negotiated on that day. Marcos distributes percentages to a network of swindlers to work with him but there are too many con artists in action luring each other.
