Six hundred feet beneath the surface terror runs deep.
On what should be a routine rescue mission during World War II, the sumbarine USS Tiger Shark picks up three survivors of a U-boat attack. But for the crew - trapped together in the sub's narrow corridors and constricted spaces - the unexpected visitors seem to spark a series of chilling, otherworldly occurrences! Starring Hollywood favourites Olivia Williams (The Sixth Sense, The Postman), Bruce Greenwood (Thirteen Days, Double Jeopardy) and Matt Davis (Legally Blonde, Blue Crush).
