Here's how Netflix describes the show: "High school isn’t the end of the world… until it is. In this post-apocalyptic, genre-bending series, the city of Glendale, California is populated by marauding gangs of jocks, gamers, the 4-H Club, and other fearsome tribes who are kicking ass as they fight to survive in the wake of a nuclear blast (on the night of Homecoming…ugh). Following an eclectic group of survivors as they navigate this strange and treacherous world, Daybreak is part samurai saga, part endearing coming-of-age story, and part Battle Royale."
In addition to Broderick, the show stars Colin Ford as our hero, 17-year-old Josh Wheeler; Sophie Simnett as Sam Dean, the most widely admired girl at Glendale High; Austin Crute as contemplative samurai Wesley Fists; Alyvia Alyn Lind as highly unstable kid genius Angelica Green; Cody Kearsley as Turbo Bro Jock, the bloodthirsty leader of the jocks; Jeanté Godlock as Mona Lisa, his badass right-hand woman; Gregory Kasyan as Eli Cardashyan (not that Kardashian); and Krysta Rodriguez as biology teacher Ms. Crumble.(Supernatural fans, in particular, will get a kick out of seeing Ford - who played young Sam Winchester - as the ass-kicking, apocalypse-surviving star of the series, especially considering that his love interest is named Sam Dean - that can't be a coincidence, right?)
The series is loosely based on the eponymous comic book by Brian Ralph, and is executive produced by Aron Eli Coleite, Brad Peyton, and Jeff Fierson.
