In an imminent and war-ravaged future, a quartet of soldiers are the sole operators of a marine outpost situated in the sea between combative continents. However, their relief is three months overdue, there's been nothing but radio silence in the interim... and already-frayed nerves are pushed to the limit as an approaching and unknown ship refuses their hails. Claustrophobic chiller from Britain stars Kate Bosworth, Thomas Kretschmann, Lucien Laviscount, Martin McCann. Widescreen; Soundtrack: English.
