A rogue submarine captain pulls together a misfit crew to go after a sunken treasure rumored to be lost in the depths of the Black Sea. As greed and desperation take control on-board their claustrophobic vessel, the increasing uncertainty of the mission causes the men to turn on each other to fight for their own survival.
