A Nazi moleman who has difficulty seeing in the light is plaguing London with a series of planted explosives targeting shelters and administrative buildings while German bombers fly overhead as a front. Cap and Bucky intervene and Bucky gets tied to a bomb while Cap disarms one placed under 10 Downing St. After Cap rescues Bucky and turns over the moleman to police, Churchill greets Cap and Bucky and requests that they stay on to fight with them. Cap thanks the PM for the offer, but tells him that their orders are to return to the states, and Bucky says that maybe they can return sometime.
