Caroline Williams returns to the DJ booth for the first time since her star-making turn in 1986's The Texas Chainsaw Massacre 2 as veteran punk rock disc jockey Amy Marlowe, bitten by a rabid bat on the eve of her final broadcast. When a raging storm traps Amy, her mysterious replacement (Nicole Kang, Batwoman) and the uneasy staff inside their small-town radio station, reality begins to fracture as they move further and further into the graveyard shift. Is it rabies? Or something far more sinister?
