555 is a 1988 horror film directed and produced by Wally Koz, and written by Roy Koz.Synopsis
While making out on the beach, a couple is attacked by a blade-wielding man dressed like a hippie. After beheading the man with a machete, the hippie slashes the woman to death with a crooked dagger, then sexually assaults her corpse. Charged with solving "the Lake Front Butcher" murders (as the media have dubbed them) are Sergeant Connor and Detective Haller, whose main suspect is the man who found the bodies, a retired army colonel named Peter Wayne. Routinely intruding upon the investigation is stubborn local reporter Susan Rather, the occasional lover of Assistant District Attorney Ralph Kennedy.
