A family discovers that dark spirits have invaded their home after their son inexplicably falls into an endless sleep. When they reach out to a professional for help, they learn things are a lot more personal than they thought.
Heidi, a blonde rock chick, DJs at the 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 from 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 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 find that the gig is far from the rock spectacle they’re expecting; the original Lords of Salem are returning, and they’re out for blood.
Lords of Salem is the third film from Haunted Films, the first two being Paranormal Activity and Insidious.
