This impressive, big budget French production, with director Antonin Baudry helming his first feature, plunges the viewer deep into the highly-charged underwater world of the submarine crew, combining the claustrophobic atmosphere of Das Boot with the nerve-shredding action sequences of The Hunt For Red October.

Lead actors Francois Civil (As Above, So Below), Omar Sy (Jurassic World) and Mathieu Kassovitz (The Fifth Element) are terrific, as the sub crew desperately attempting to prevent an international catastrophe, despite being only ‘small cogs in a big machine’. The plot twists and turns like an eel, and the sophisticated military hardware is stunningly realised.
