Lexx (1997)

S3E8 The Key

Aboard the Lexx, Stanley decides that the simplest way to get the ship operational again is to blow up Fire and have the Lexx consume the wreckage. He instructs the ship to prepare to fire when it's aimed at the planet. Meanwhile, Xev insists that she deserves a chance to be captain and begins searching for methods to transfer the captain's key from Stanley to herself.
