It all starts in an overcrowded prison, where Diego is being held on a charge of kidnapping. Diego's lawyer secures his release, but his freedom comes at a price: he must join forces with a brutal psychopath and hold up an armoured truck. A hilarious caper ensues, as the robbery swiftly degenerates into mayhem and violence. While the men appear to be engaged in a perverse competition to see who is the most incompetent, Ursula Lopez, an amateur criminal with an insatiable appetite, and her rival, Captain Leonilda Lima - reveal themselves to be the true protagonists.
