June 1940. With England on the brink of invasion, a reluctant young hero leads a team of robot commandos to take the fight back to the enemy, but with dissention in the ranks, a traitor in their midst and his nemesis hot on their heels, the odds are against them. June 1940. After an insanely heroic rearguard action, Jack Stone and his friend, Billy Briggs, escape Dunkirk by the skin of their teeth with the remnants of the British Expeditionary Force, leaving Jack's nemesis, General Ernst Mörder, immolated but alive. As France falls, Great Britain's invasion appears imminent. Haunted by his brother's death at Mörder's hands, Jack is recruited by Winston Churchill to lead his first team of commandos. In Berlin, Adolf Hitler resurrects Mörder, an old comrade, ordering that he oversee a top-secret project in Norway. Hell-bent on revenge, Mörder is re-born, concealing his disfigurement with a grotesque crimson samurai mask. Flown to the Scottish Highlands to meet their team, Jack and Billy join Brigadier Charles Hastings and sassy American scientist, Doctor Cammy Sullivan, who introduces them to the Tin Can Tommies--four humanoid machines who fought for the Allies during the Great War--nicknamed Lancaster, Hurricane, Mosquito and Spitfire.

Distraught at McNulty's loss, Jack spirals into depression. Introducing him to the crawlers, the team's single caterpillar-tracked motorcycles, Cammy challenges Jack to a race across the Highlands where she persuades him that the Tommies can take the fight to the enemy. Falling for Cammy, Jack commits to lead the team who are posted to Dover for paratroop training under maverick young Spitfire ace, Alan 'Nosy' Parker, and his pilots of 2 Squadron, and meet Sal 'Fixer' Remmy, the wise-cracking pilot of their new vehicle, the Valiant, a modified Flying Fortress. After a skirmish with a German U-boat off the English coast, the team earn 2 Squadron's respect and training begins in earnest. Jack and Cammy grow closer as the team's first mission is revealed--the destruction of a Hydropower plant in Vemork, Norway, to prevent the creation
