On a routine delivery mission, the crew of a merchant ship is suddenly attacked by an armada of undead soldiers aboard a swarm of ships under the control of Commander Brakka, an ancient zombie with highly advanced technology stolen from a long-dead civilization. The crew of the freighter struggles to stop the invaders, but they are quickly consumed by the massive hoard.

From one star system to the next, the zombie armada conquers all in its path, gobbling up everything and everyone who stands in its way. Despite its best efforts, the strongest galactic power, the Tioran Federation, is unable to stop Brakka’s overwhelming invading force.

Five crew members aboard the Starcruiser Galaxy, Captain Mintax, Engineer Glenda Ritan, Weapons Specialist Steve, Programming Specialist Jonn Brock, and Communications Specialist Andre “Goober” Gu’ber hold the only key that can stop Brakka from transforming galactic citizens into his zombie minions — or lunch for his crew. As the facts unfold on Brakka’s ascension to power, the crew of the Galaxy learns of their involvement in creating the malevolent monster.

To correct their mistake, the Galaxy’s crew must time travel to the past to a point before Brakka obtained his massive armada if they hope to defeat him in the future and set the universe right once again. .
