The attempted robbery of the armoured car in the back streets of Montevideo is a miserable failure. A lucky break for the intrepid Ursula Lopez who manages to snatch all the loot, more hindered than helped by her faint-hearted and reluctant companion Diego. Only now, the wannabe robbers are hot on her heels. As is the police. And Ursula's sister. But Ursula turns out to be enormously talented when it comes to criminal undertakings, and given the hilarious ineptitude of those in pursuit, she might just pull it off.
