Welcome to Undead Park

America’s largest theme park has become a sprawling nightmare after a devastating zombie virus sweeps through the grounds. Sung-heon, an ordinary father, suddenly finds himself trapped inside the chaotic attraction alongside his young daughter. Surrounded by hordes of the undead and foreign tourists he cannot communicate with, every moment becomes a desperate fight for survival in an environment designed for entertainment but now transformed into a deadly labyrinth. This outbreak is unlike any known disaster. The infection does not discriminate; every living creature that moves—human or animal alike—is violently turned into a ravenous monster. Severely hindered by an injured leg, Sung-heon must push past agonizing pain and physical limitations to protect his child from the relentless horde closing in around them. With escape routes cut off and communication impossible, the situation deteriorates rapidly. Trust fractures among the stranded survivors as panic sets in. To make it out alive, Sung-heon and his daughter must battle not only the terrifying undead swarming the park but also the unpredictable, desperate actions of the other trapped humans fighting for their own lives.
