Existential Box — Ann Mayburn

Lose yourself in absolute darkness, cradled in the watery womb of a sensory deprivation tank and find the secrets of the universe locked within your own mind. Unfortunately for Rex Ruso, a famous Hollywood producer, his time in the tank becomes a torturous exercise in physical pain and mental anguish when the lid on his tank refuses to open and no one is there to let him out.
