When a severed human hand is found at a weekend film festival, the actual cast and crew of the CRUEL SUMMER trilogy suddenly find themselves thrown into the middle of a real-life sequel engineered by an unhinged psychopath.

Survivors of the bloody "theatre massacre" years earlier must fight for their lives as members of their psychiatric hospital's therapy support group begin falling prey to an unseen psychopath. Deep secrets are uncovered and old friendships are tested as they realize the killer may actually be much closer to them than they ever thought possible.
