Cliff flies to the rendezvous, where Sinclair demands Cliff hand over the rocket pack, but Cliff divulges to Eddie and his gang that the actor is a Nazi, and the evidence quickly backs Cliff up. The infuriated Valentine and his gang turn their weapons on the seemingly off-guard Sinclair and Lothar, but Sinclair summons a troop of heavily armed Nazi S.A. hidden at the observatory. The Nazi rigid airship "Luxembourg" (under the guise of a peace mission) appears overhead to evacuate Sinclair. FBI agents suddenly announce their presence, having secretly surrounded the area; they and the mobsters join forces to battle the Nazis. Sinclair and Lothar escape, dragging Jenny with them aboard the airship.
