Waterworld
Helen learns that the Mariner knows where Dryland is and wants to see it. The Mariner puts her in a diving bell made out of plastic and swims down to a sunken city (actually the city of Denver) to show her. While they are looking at the sunken city, the Smokers find the Mariner's vessel and take control of it. Enola hides on the ship. When the Mariner and Helen return to the surface, the Smokers capture them. The Deacon wants the Mariner and Helen to tell him where Enola is, but they will not help him find her. The Deacon pretends to kill the Mariner and Helen by firing a gun into the sky. This scares Enola out of hiding and she is captured by the Smokers. The Deacon has his crew burn the Mariner's vessel and shoot at them, but they escape by diving deeper underwater than the bullets can reach. Since the Mariner can breathe underwater, he "breathes" for both of them using a kiss.
