Set in the same universe as “The Walking Dead,” “Fear the Walking Dead” is a gritty drama that explores the onset of the undead apocalypse through the lens of a fractured family in Los Angeles. 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 (Dickens) and English teacher Travis Manawa (Curtis) have managed to assemble.
