In May 1940, Corporal Raines (Danny Dale Danny Dyer) and his three comrades-in-arms were asked by an officer to participate in the fight against the German army on their way to Dunkirk. Raines disobeyed orders and was sent to a military prison. In Naval Intelligence, Major Jones (Sean Bing Sean Bean) is assigned a highly classified task: German radar technology is ahead of European countries, radar stations along the Atlantic coast form an invisible network, and Jones is ordered to form a special force to destroy German receiving stations. Jones fished out his old subordinate Raines in the military prison and took Raines "on the way". In the highlands of Scotland, Jones trained the special operations team such as Raines strictly. This mission has only one chance, and the deficiency in the early stage can lead to the end of the whole game. The special forces finally landed in Norway and got in touch with the local guerrillas, and the final test officially began.
