Luca Morandi, a well-known non-violent thief, has no choice but to do a job for the police: opening the vault of the headquarters of the Northern Bank, in Barcelona. There, there is a database that may give proof of a link between the magnate Joe Fortuna and a series of international crimes. Luca and his two partners, Michele and the inexperienced Ricky, plan the theft, while Luca becomes closer to Anna, Joe Fortuna's partner. But Luca cannot imagine that Anna is an infiltrator of the police and that their relationship may endanger all the operation.
