With the help of his wannabe filmmaker roommate Matt (Josh Gad) and the sexy med student Cassie (Krysten Ritter), who first discovers Drex as he unzips himself from his own body bag, the three begin to uncover leads about why his death didn’t stick, why a mystery online chat buddy is after him and why he’s starting to show signs of superpowers. Will they figure out why Drex is only sort of dead? Will Cassie discover ancient Zombie secrets? Will Matt get a film career out of it? Or is falling in love actually what Drex needs to do to stay alive?
