A young man and his boyfriend are hanging out at the Bunkers. Decades ago, it was constructed to be used as a shelter for a war that never came. It was eventually repurposed into an underground mall. It is an unassuming Saturday morning in the middle of March when an unanticipated alarm warbles. Large doors come down sealing the visitors inside and outside communication halts. Their situation gets more bizarre as everyone starts turning into anthropomorphic gorillas.
