Attack of the Radioactive Zombies

In the wake of a cataclysm that has ravaged the Earth, the lingering radioactivity brings the dead back to life. With no effective way to eliminate the zombies, a mysterious organization known as Undead Manor proposes a "solution." The facility's leader offers families a way to manage their undead relatives by placing them in "memorial cells." However, when a group of visitors comes to tour the manor, they soon realize that this service comes with dire consequences. As the undead begin to break free from their confines, the guests must unite to survive the onslaught of the "Radioactive Zombies."
