El patrullero 777

Diógenes Bravo (Cantinflas) walks his patrol through a police department where most of the other officers have gone corrupt and stopped caring about the citizens they serve. He does the job the right way, and he settles each call with a method of his own. Miguel M. Delgado, who made the earlier Agente 777 pictures with Cantinflas, puts Claudia Loza (Ana Bertha Lepe) and Lupe (Valeria Pani) in his path, and Diógenes keeps to his honest rounds.
