Director Kasra Farahani has released a haunting trailer for his upcoming thriller The Good Neighbour. The film follows two tech-savvy high school teenagers, Ethan and Sean, who attempt to prank their elderly neighbour Harold Grainey (James Caan) by convincing him that his house is haunted. The mischievous duo breaks into Grainey’s house one day to install equipment to create the illusion of ghosts, as well as to set up hidden cameras to document their neighbour’s reaction. The two of them soon realize that they have targeted the wrong person when they discover that Grainey is actually a cold-blooded psychopath.

Scheduled to hit theaters on September 16, watch the trailer of The Good Neighbour above.
