In a wasteland swarming with undead hordes, survival depends on gaining entry into fortified citadels. Zoe marries unassuming drifter Leo to secure mutual protection on the road, but immediately casts him aside when wealthy permit-holder Jasper offers her sanctuary. Blinded by greed, Zoe publicly mocks Leo as a useless parasite and leaves him to be torn apart outside the fortress gates.
Zoe has no idea that Leo is the reclusive founder and sovereign commander of the entire Golden Lion Citadel. Disgusted by her deceit, Leo turns his back on his ungrateful ex and unites with Serena, the valiant ruler of Hope Haven who has sought him for years. Together, they command elite survivor armies, leaving Zoe to realize the drifter she discarded ruled the world.
