It's 1991, and Sasha, Hayley, Tiffany and Jessica are four best friends into black clothes and rock music. They dabble in ouija boards and occult games like 'light as a feather.' But when Hayley gets 'saved', she's convinced rock music is satanic and conspires to save them all. Her good intentions go up in flames and the four girls accidentally summon the devil. Trapped in the basement with entities beyond their wildest nightmares, their only saving grace is rock & roll. They have to hope to hell it's enough, before another one bites the dust.
