Starhyke - Season 1 Episode 3 Kill Jill

The Nemesis is infiltrated by a Reptid/Human hybrid from a future even more distant than their own. As Captain Blowhard tries to figure out what to do with him, the ship is stricken by a sudden irreversible loss of power and descends through the Earths atmosphere. The Nemesis and its crew crash land on a desolate part of Earth, where they are unable to get the ship operational again. They build a colony and live happily for almost 3 decades until an opportunity arises leaving Blowhard only seconds to prevent the chain of events that originally left them marooned on the island.
