Soon after losing his salvage job, former naval officer Robinson (Jude Law) assembles a misfit crew of unemployed sailors for a risky mission: Find a sunken Nazi U-boat, rumored to contain a fortune in gold. Promising each man an equal share, Robinson leads the mixed British and Russian crew to comb the depths of the Black Sea. Before long, greed takes hold of a crew already divided along language and cultural lines -- and the fewer men that make it back alive, the more gold to go around.
