In July 1942, convoy PQ17 sets out from Iceland with thirty-five merchant ships carrying tanks, planes, and supplies bound for the Soviet Union, escorted by British warships wary of the German battleship Tirpitz lurking in Norwegian waters. Fearing an imminent attack from the Tirpitz, the Admiralty orders the convoy to scatter, a decision that strips the merchant ships of protection and leaves them exposed to German U-boats and Luftwaffe bombers across open Arctic sea. Jeremy Clarkson presents the account, drawing on survivor testimony, expert interviews, and reenactments to walk through how the order unfolded and what it cost: only eleven of the thirty-five ships reach Archangel, the rest sunk one by one over the following days. The film weighs the naval intelligence behind the scatter order against its consequences, asking whether caution about a battleship that never actually attacked turned a defensible convoy into one of the war's costliest maritime disasters. Winston Churchill later called it one of the most melancholy naval episodes of the war.
