After an almost-apocalyptic zombie outbreak, humans have won the war and are exploring how humanity can recover after such a huge percentage of the population has been wiped out. Humankind finally has the upper hand, but Melanie, who lost her entire family, is still deeply traumatized. In a bid to overcome the demons of her past, she goes on a zombie safari retreat. It is the ultimate in therapeutic revenge.

"The ReZort" is actually a highly controlled and monitored environment with a maze of concealed security cameras, restraints, and barriers. The eyes and ears of trained security personnel are on the guests 24/7, ensuring a safe shooting distance between the living and the undead-that is, until the resort's security system is hacked and a computer virus crashes it, potentially unleashing thousands of bloodthirsty zombies back into the wild.
