Frank Dillane

It's a gritty drama that explores the onset of the undead apocalypse through the lens of a fractured family. Set in a city where people come to escape, shield secrets, and bury their pasts, a mysterious outbreak threatens to disrupt what little stability high school guidance counselor Madison Clark and English teacher Travis Manawa have managed to assemble.

The group aboard the Abigail is unaware of the true breadth and depth of the apocalypse that surrounds them; they assume there is still a chance that some city, state, or nation might be unaffected -- some place that the infection has not reached. But as Operation Cobalt goes into full effect, the military bombs the Southland to cleanse it of the Infected, driving the Dead toward the sea. Just because zombies can't swim, doesn't mean there isn't...

In Season Four, viewers will see the world of Madison Clark and her family through new eyes, the eyes of Morgan Jones, who is joining the story. The characters' immediate pasts mix with an uncertain present of struggle and discovery as they meet new friends, foes, and threats. They fight for each other, against each other, and a legion of the dead, and work to build an existence strong enough to resist the crushing pressure of living coming apart....
