Hard man Big Mo rules family and friends with a rod of iron.

From his base in a rundown area of London, he is driven by a desire to emerge from the shadow of his career criminal father and lift his family out of the poverty trap.

When a warehouse raid turns up more than he bargains for, Mo finds himself in possession of the weapons he needs to transform himself from petty criminal to big-time armed robber.

Planning the ultimate raid, Mo seems to have everything under control until Prime Minister Margaret Thatcher orders British troops – including his younger brother Clive – to war in the Falklands.

As Mo fights the police and his own vicious temper, Clive faces a battle for survival in the desolate south Atlantic.

Eventually their two worlds will collide, threatening Mo and all he holds dear.
