The Secret Adventures of Jules Verne - Season 1 Episode 16 The Rocket's Red Glare

The group is summoned to British Columbia after an American General, Steele, is kidnapped by Indians from the British territory. To avoid a war between the two countries, Fogg and the others must find Steele. They discover that Steele's kidnapping was engineered by Count Gregory and the League of Darkness. The League steals the Aurora and drops Steele's corpse off at West Point to further set the two countries upon each other. With the aid of a local Indian, the team finds Gregory's waterfall hideout, from which he plans to launch a rocket and destroy West Point as President Lincoln gives a speech. Despite Phileas' reluctance to engage Gregory (since the Count killed his beloved in the episode "Southern Comfort"), Rebecca enters the hideout only to be captured. She is tied to the rocket and launched. She manages to escape and redirect the rocket, while Fogg and Verne break free of Gregory and knock him back into the waterfall where he plunges to his seeming death.
