Movie theaters are a magical place, and the Downtown Nickelodeon is no exception, as junior film archivist Muriel Sharpe is about to find out. Tasked with the job of going through the old theater's archives before the building is demolished, Muriel doesn't hold out much hope of unearthing anything rare, but what she finds is a treasure trove of long-thought-lost films. Acting on instinct, and against her better judgement, she threads up the old movie projector and inadvertently awakens the magic of the old Nick. She's swept away in a passionate romance, dodges bullets with an infamous gangster, but nothing could prepare her for the horror the theater unleashes with Shriek of the Harpy, and soon she's in a fight for her very life as she tries to escape the one place she considered to be a safe haven.
