Storyline

Heidi, a blond rock chick, DJs at a local radio station, and together with the two Hermans (Whitey and Munster) forms part of the "Big H Radio Team." A mysterious wooden box containing a vinyl record arrives for Heidi, a gift of the Lords. She assumes it's a rock band on a mission to spread their word. As Heidi and Whitey play the Lords' record, it starts to play backwards, and Heidi experiences a flashback to a past trauma. Later, Whitey plays the Lords' record, dubbing them the Lords of Salem, and to his surprise, the record plays normally and is a massive hit with his listeners. The arrival of another wooden box from the Lords presents the Big H team with free tickets, posters and records to host a gig in Salem. Soon, Heidi and her cohorts are far from the rock spectacle they're expecting. The original Lords of Salem are returning and they're out for blood.
