Small-time swindler Marcos (Ricardo Darín) observes Juan (Gastón Pauls) pulling off a scam on a cashier, and then getting caught as he attempts the same trick again. Claiming to be a policeman, Marcos drags Juan out of the store, then reveals himself to be a fellow grifter with a higher stakes game in mind, and invites Juan to be his partner. When an old time con-man enlists them to sell a forged set of extremely valuable rare stamps,"The Nine Queens," the tricky negotiations that ensue introduce a cast of suspicious characters including Marcos' beautiful sister Valeria (Leticia Brédice) and their innocent younger brother Federico (Tomás Fonzi). As the deceptions and duplicity mount, a slew of thieves and con artists make it difficult to figure out who is conning whom.
