Tak, the group's leader and mastermind behind their ill-fated game of hide-and-seek at the abandoned "Kijsada Paradise" water park, leads his friends Park, Tee, Melon, and Ohm into a nightmare that resulted in the mysterious disappearance of Jod, a special-needs friend within their circle. A fleeting act of bravado leads to ultimate horror when the very person they once called "friend" returns to haunt them, bent on taking their lives. Forced to return to the park to find a way to put an end to the terror, they remain oblivious that this is merely the beginning of their nightmare, as they are compelled by Jod to play a deadly game of "Hide-and-Seek for Survival." Once the "Seekers," they must now become the "Hiders." This ultimate test of friendship forces them to join forces to rectify the consequences of their past actions and unravel the many dark secrets buried deep within the cursed, abandoned water park.
