[Season 1 !Season 2 !Season 3 !Season 4 ]
Nick Clark (Frank Dillane) is a drug addict in Los Angeles. He wakes up in a drug den, having just shot up with a new narcotic. One of his fellow junkies must have overdosed, because she starts to eat the others. Nick gets out, but ends up in hospital.
In hospital, Nick refuses to cooperate with the cops. However, he does talk to his stepfather Travis Manawa (Cliff Curtis - Hercules: The Legendary Journeys ). But when Travis checks out the drug den, there are no zombies or corpses. Has someone cleaned up the crime scene before the cops could find it?
We also meet Nick's mother Madison ( Kim Dickens ) and sister Alicia ( Alycia Debnam-Carey ). Since the zombies are in the background, as they are in the later events portrayed in The Walking Dead , this is mostly a soap opera establishing the characters.
In the second half of the story, Nick escapes from hospital and goes looking for his drug dealer. His assumption is that the zombie outbreak was caused by a new drug. A running joke among fans is that it was the blue meth from Breaking Bad.
There is an incident that is televised on the news channel, and it goes viral on the Internet video-sharing sites. Of course, nobody realizes that it is actually the start of a zombie apocalypse.
The National Guard have been using the codeword Cobalt. Daniel Salazar (Rubén Blades - Predator 2 ) wants to know what it means.
