The early life of Ian Fleming, the creator of James Bond, is explored. In the opener, Fleming begins work with British naval intelligence and cooks up a scheme to get information from two captured German submariners.

A mischievous Ann invites Fleming to Esmond's birthday party, and although Fleming has brought Muriel as his date, sexual chemistry sizzles between them. Meanwhile, France is looking like it's about to crumble against Nazi forces. Office bound and desperate to be a man of action, Fleming urgently tries to persuade Godfrey to send him to France to oversee the destruction of secret files at one of their bureaus. To his surprise, Godfrey accepts. Fleming sets-off on his mission, but when unexpected obstacles arise, how will he handle the dangerous consequences?

While training at a camp in Canada (Camp X), the Americans ask Fleming to use his talents to write a blueprint for a Central Intelligence Agency. On his return to London, Fleming persuades Godfrey to form the 30 Assault Unit - a group of the toughest soldiers prepared to play dirty, with Fleming serving as commanding officer. He believes the new unit of Intelligence Commandos is the key to beating the Nazis. Meanwhile, Fleming continues his relationship with Ann, but refuses to consider taking it to the next level, while Rothermere makes it clear he intends to win her over once and for all.

The war is nearly over, but Fleming is convinced the Nazis are hiding nuclear plans and that the British need to find them before the Russians. Finally, Fleming is granted permission to go to Germany to attempt to retrieve the plans. He succeeds in tracking down the documents, but comes face to face with The Werewolves (renegade German soldiers who will die before giving up the cause). Back in London, celebrations are underway, but the arrival of peace also means wartime relationships will have to be reassessed. Will Fleming and Ann finally find a way to be together? Moreover, with the war in its final throws, Fleming's days in Naval Intelligence are numbered - what other ways will he find to channel his ingenuity and imagination?
