A research team encounters multiple threats while exploring the depths of the ocean, including a malevolent mining operation.

When cyber-genetically enhanced anarchist Brixton (Idris Elba) gains control of an insidious bio-threat that could alter humanity forever — and bests a brilliant and fearless rogue MI6 agent (The Crown’s Vanessa Kirby), who just happens to be Shaw’s sister — these two sworn enemies will have to partner up to bring down the only guy who might be badder than themselves.
