Watch Pepeng Shotgun (1981) Official Trailer

The feud between the Medranos (poor but respected in the society) and the Sablantes (wealthy and corrupt) dates back to World War II where Joaquin Sablante was a Japanese collaborator while Pablo Medrano was a guerilla leader. The feud erupts anew when Pepe Medrano accidentally shoots Rex Sablante in a night club and when Pablo opposes Manolo Sablante's mayoral bid. Elected through fraud, Manolo has had Pablo killed, thus beginning a string of murders and counter-murders which eventually wipes out both families.
