Un cura de locura(1979)

A newly ordained priest, Capulina, is sent to a town where a gang of criminals has driven out the priest who needs to be replaced. Rogelio, the gang’s leader, forces Capulina to take part in a robbery, and the police mistake him for the gang’s leader, calling the group “the priest’s gang.” Capulina must set the record straight and catch the gang on his own.
