Plot Summary

After a decade of hard work at a marine salvage company, the recently redundant submarine captain, Robinson, decides to risk everything in search of a fabled underwater treasure: a sunken Nazi U-boat laden with gold ingots of inestimable value. Bent on unearthing the unclaimed prize under the nose of the Russians and their hostile naval fleet, Robinson assembles a hand-picked mixed crew of antagonistic experts to comb the vast seabed of the cold Black Sea in a rusty Soviet submarine. However, as greed gets the best of the already divided team, the promise of an equal share rapidly starts to fade away. Can Robinson's men resurface in one piece, and, above all, rich?
