The Krang constantly attacks Alpha Centauri. Continuous fleets are arriving in Alpha Centauri through the wormhole and going to Andromeda. Humans, ShanTu, and Fazuli, fight a battle that appears hopeless. The Krang appear relentless in their attempts to conquer the inhabitants of Alpha Centauri, and victory would give them a foothold in conquering the Milky Way.

Samantha Stone returns from her rescue efforts in the Pegasus star system, which is already under Krang's control. Her starships would bolster the Alpha Centauri starships but would prove inadequate to stop the Krang. Jack L. Allan's fleet was needed.

Jack L. returns to assist the Alpha Centauri fleets ahead of his force. Freedom and Heritage considered all options to stop the Krang and found only one sure way. Someone would have to enter the wormhole and blow it up, and they would surely die. Jack L. realizes the only option to complete that would be if he and Freedom dropped depth charges in the wormhole.

Jack L. has Freedom 'Shift' all of the crew to Heritage and begins a run at the wormhole. As Freedom begins entry into the wormhole, depth charges are dropped and continue to drop once Freedom is entirely in the wormhole.

A massive explosion causes the wormhole to collapse, and Jack L.'s fate is unknown.
