Overview
The Redeemer, also known as The Redeemer... Son of Satan! and Class Reunion Massacre, is a 1978 American horror film directed by Constantine S. Gochis. It follows a group of people trapped inside their high school during a ten-year reunion who are being killed off by a mysterious killer known as The Redeemer.
Plot
A young boy, named Christopher, emerges from a rural lake, fully clothed, and walks to a road where he is picked up by a shuttle bus and taken with other young boys to a local church where they are part of the boys choir. During the church service, the preacher, known only as the Redeemer, arrives and gives a hate-filled sermon about the sins of the world and of six people who have lived their life of sin, each of them 1967 graduates of the now-shuttered Stuart Morse Academy.
The six individuals receive invitations to 10-year high school reunion: John Sinclair, an unscrupulous and corrupt lawyer; Cindy, a freewheeling party girl; Terry, a glutton and slacker; Jane, a wealthy and shallow heiress; Roger, a vain film actor; and Kirsten, a closeted, self-loathing lesbian.
At the school, a mysterious man arrives claiming to be a property inspector and is let into the building by the janitor. The man then shoots the janitor to death in the swimming pool area and, after hiding the body, makes a plaster mold of the janitor's face to make a latex mask for himself.
