4x4 is an Argentine-Spanish crime thriller film based on actual events by Mariano Cohn from a screenplay he co-wrote with Gastón Duprat. Produced by the latter, the film stars Peter Lanzani as Ciro, a criminal who breaks into a 4x4 pickup truck owned by an obstetrician medic Enrique Ferrari (Dady Brieva) in order to steal a car stereo. The truck had a security mechanism that cuts the power, trapping Ciro in the process.
