In the dark silence of the sea during World War II, the submarine USS Tiger Shark prowls on what should be a routine rescue mission. But for the shell-shocked crew, trapped together in the sub's narrow corridors and constricted spaces, this is about to become a journey into the sensory delusions, mental deceptions and runaway fears that lurk just below the surface of the ocean.
