Rumored to have used footage salvaged from a commercial studio dumpster, the film is a commentary on Filipino onscreen macho culture and one of the rare surviving works in the brief filmmaking career of Ramon ‘RJ’ Leyran. It was a product of the last Christoph Janetzko film workshop, with a focus on experiments with optical printers, held in 1990.
