While patrolling the Atlantic in 1943, an American naval submarine rescued three survivors left adrift from the sinking of a British hospital ship. Soon afterwards, however, the crew of the sub was beset by strange occurrences, from ghostly images to fatal accidents. As fear and paranoia brew amongst the sailors, the unholy reasons why spill out in this wartime chiller co-written by Darren Aronofsky; Bruce Greenwood, Matthew Davis, Olivia Williams, Zach Galifianakis star. 106 min.
