Set against the backdrop of 1999, when widespread doomsday fears gripped the public, the story follows the unexpected rise of unlikely heroes in Haeseong City. Eun Chae Ni, a spirited and unpredictable young woman living with her grandmother Kim Jeon Bok, finds her ordinary life upended when she and her neighbors, Son Gyeong Un and Kang Ro Bin, become entangled in a mysterious incident that grants them supernatural abilities. However, their newfound powers are unstable and far from perfect. As unease spreads across the city, the trio must navigate their limitations while stepping into roles they never intended to take on. Amid a series of unexplained disappearances, they join forces with Lee Un Jeong, a principled yet socially distant civil servant from Seoul, whose involvement adds further complexity to the unfolding mystery. As they investigate the growing threat, they encounter Ha Un Do, a composed and rational figure concealing darker intentions. With Haeseong City’s safety at stake and tensions escalating, this unlikely group must confront both external dangers and their own shortcomings in a race to preserve peace in an increasingly uncertain world.
