Astronaut John Crichton attempts to use the Earth's atmosphere to propel his module at high speeds. He is hit by a radiation wave and is sucked through a wormhole into a distant part of the universe--straight into the middle of a space battle.

The Scorpius clone puts John into a dream world to prevent the Scarrans from getting any wormhole knowledge.

Crichton falls into a wormhole and meets up with a strange man who shows Crichton the consequences of wormhole travel.

Moya arrives at Earth in present day, Christmas. The crew show their ships and technology to Earth's scientists. Crichton starts writing a journal. The creature left on board Moya by Grayza manages to get to Earth where it starts killing and hunting down Crichton.
