Andrew introduces his boyfriend to his childhood friends by playing a nostalgic - and terrifying - game of Hide and Seek. The game turns deadly when he discovers someone from his past hiding in the shadows, out for violent revenge. Because as seductive as nostalgia is, it can also be a toxic force, when the comfort of the past gets thrown up against the real world, with all its danger, fear, and uncertainty, and all of its blood, sweat, and tears.
