Steve MacKendrick (Alan Ladd), nicknamed "Canada" because he claims he is from the country, volunteers in 1940 for the British military's parachute training facility.
Both Penny and his new commander, Major Snow (Leo Genn), see potential (and a mystery that does not add up) in him, despite his strong efforts to avoid assuming any responsibility.
An RAF radar expert, Flight Sergeant Box (John Boxer), accompanies the raiders to retrieve a key component to take back to Britain.
He tells Penny that he resigned his commission from the USAAF after ordering his best friend and co-pilot to parachute out of their bomber when an experimental rocket got stuck.
Although Snow and most of the men get out, the regimental sergeant major (Harry Andrews) dies from the wounds he received when he entered the minefield.
