Los chicos del maíz (Children of the Corn)

A child preacher named Isaac travels to Gatlin, a small town in Nebraska, and manages to get the children there to murder all the town's grown-ups. Soon after, a young couple traveling around the area stop in town to report a murder, but the whole place appears to be deserted. They soon encounter a pagan cult led by children and teenagers. Iconic and festive cross between American gothic and folk horror, based on a story by Stephen King.
