chunk: Coffey but Coffey escapes in a mini-sub with the primed warhead, and Bud and Lindsay give chase in the other sub. Coffey is able to launch the warhead into the trench, but his sub is damaged and drifts over the edge of the trough, and he is crushed when the sub implodes from high pressures. The other mini-sub is also damaged and is taking on water; with only one functional diving suit, Lindsay opts to enter deep hibernation when the ocean's cold water engulfs her, and Bud swims back with her body to the platform. There, he and the crew administer CPR and revive her. Bud and Lindsay reaffirm their lost love.
