Sheri Moon-Zombie plays Heidi, a blond rock chick, who 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 to spread their word. As Heidi and Whitey play the Lord’s record, it starts to play backwards, and Heidi experiences a flashback to a past trauma.
Later, White plays the Lord’s 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 or Salem are returning and they’re out for blood.
