Lt Rose is persuaded by a woman to give her a tour of his battleship. She enlists the support of her fellow spies, one of whom dresses as woman, who tour the ship and steal the code book. Such is the Royal Navy's determination to retrieve the book that they open fire on the spies in their rowing boat. When that fails, they pursue them on land, and finally open fire on the escaping enemy battleship.
