Something is missing in Tom's life. His marriage has lost its spark, his job is suffocating him, and his childhood best friend Dan still clings to the past. Every day he goes through the motions, becoming increasingly detached from those around him. Dan has the solution... something Tom's got to see to believe... tonight. What Dan shows him leaves Tom unsettled, flooding his mind with disturbing images, and binding the two friends together with its ugly secret.
