Robert, Maryam, and Kylie are excited to be at a sleepaway cheer camp. But then their bunkmates–and main cheer competition–try to convince them their cabin is haunted. The three friends laugh it off until some suspicious things start happening. Flickering lights, getting locked in the bathroom, vandalized poms could all be the work of a cheer competitor … or is it the Cabin 4 ghost? Robert is convinced he knows who’s to blame, but will he be able to prove it?
