Despite the dramatic collision at the conclusion of chapter seven of Universal's Adventures of Smilin' Jack, chapter eight reveals that the Japanese freighter only grazed the submarine carrying Jack (Tom Brown), his friends and the incognito Axis agent Fraulein Von Teufel (Rose Hobart) -- but enough for the vessel to take in water. The freighter captain (Edward Peil Sr.) is ordered by radio to take Jack and his fellow passengers prisoners and once and for all force Mah Ling (Cyril Delevanti), the governor of Mandon, to reveal the whereabouts of the secret passage from China to India. Onboard the vessel, Fraulein Von Teufel quickly establishes her identity with the freighter captain and his second in command (Wheeler Oakman), and orders them to dispose of Mah Ling without delay. Meanwhile, our friends find themselves imprisoned in a cabin complete with a rowboat and a launch. Saying goodbye to Mah Ling, Tommy (Edgar Barrier), Janet (Marjorie Lord), and a dazed Fraulein Von Teufel, whom the crew had manhandled to "let it look real," Jack and Wing (Keye Luke) remain onboard to somehow warn the Americans about the impending attack on Pearl Harbor, the vessel's ultimate destination. Jack manages to get hold of the radio and with no thoughts to his own and Wing's safety, suggests that the vessel be blown to kingdom come.
