After a mysterious comet crashes from the sky, the Teen Titans decide the local mall is the perfect place to hang out and investigate the fallout. Robin has a theory that a zombie outbreak is about to happen, and everyone knows that zombies cannot resist a trip to the mall! But the situation quickly spins out of control. As the bargain hungry undead swarm the streets, Robin and his team must step up to save their beloved city. The danger is everywhere, the cemetery is definitely not safe, rival villains are getting caught in the mess, and some of the Titans are coming down with a serious case of shopping fever. Robin must figure out how to keep his distracted team focused long enough to cancel this hilariously terrifying apocalypse.
