The film is set in the Midwest against a backdrop involving a killing spree thought to be orchestrated by a satanic cult. Three best friends embark on a road trip to a heavy-metal show, where they bond with three aspiring musicians and head off to one of the girls’ country home for an afterparty. A night of fun and youthful debauchery takes a deadly turn as bodies begin to pile up, with each side thinking the other hides the killer.
There is some very explicit gaslighting. One of the characters uncovers a shocking truth and another character says "you're so lost, you don't even know what's real anymore."
Three characters are given sedatives and gradually collapse onto the ground, sedated/asleep. They wake up restrained with rope in a very scary situation.
