About

Across South Korea, various superhumans live among ordinary people. Among them are three twenty-year-old friends who are constant magnets for trouble. Yoo Hwayoung, known as 'Firefly,' who manipulates flames from her hands; Myung Yijin, known as 'Ghost,' who passes through walls and doors like a phantom; and Kang Hyeji, known as 'Mountain Ogre,' who possesses unimaginable superhuman strength. These three powerful individuals are an inseparable crew of best friends. However, despite their immense power, they are still immature twenty-year-olds. Lacking the wisdom to know where and how to use their gifts, they often cause accidents by using their powers for pranks. Tonight, their eyes are set on an amusement park where all the lights have been turned off after closing. "No one's here, so why don't we just play by ourselves for a bit?" Driven by curiosity and mischief, the three sneak into the park using their powers. At first, they are thrilled to have the entire park to themselves, but their pranks grow increasingly bold. They use super strength to move rides, flames to light up the darkness, and phase through restricted areas until, inevitably, disaster strikes. Rides are damaged and fires begin to spread throughout the facilities, turning their midnight escapade into a major accident in an instant. Detecting this dangerous use of superpowers, the Korea Superhuman Management Bureau (KSMB), a government agency, begins to move. KSMB agents arrive on the scene, surrounding the park and demanding their surrender. Flustered by the sudden turn of events, the three girls brandish their powers to threaten and resist the agents, but they are eventually subdued by the KSMB's response. Caught by a government agency for a single night of immature mischief, what fate awaits these three superhumans?
