A rogue submarine captain pulls together a misfit crew after being laid off from a salvage company to go after a sunken treasure rumoured to be lost in the depths of the Black Sea. As greed and desperation take control onboard their claustrophobic vessel, the increasing uncertainty of the mission causes the men to turn on each other to fight for their own survival. Black Sea is directed by Kevin Macdonald (The Last King of Scotland, How I Live Now) and written by Dennis Kelly, creator of the cult Channel 4 series Utopia.
