The story begins in the fictional town of Haeseong City during the height of the apocalyptic Y2K doomsday panic. Eun Chae-ni is a terminally ill woman who wants to travel the world before she dies. Desperate for money, she convinces her neighbors, Son Gyeong-hun and Kang Ro-bin, to help her fake her own kidnapping for ransom cash

The scheme goes entirely wrong. They accidentally crash into a toxic trash dump. Unbeknownst to them, the dump contains hazardous runoff from the "Wunderkinder Project"—a secret, illegal human-experimentation laboratory run by the ruthless Dr. Ha Won-do. Instead of dying from the chemical exposure, the three misfits wake up with bizarre, highly restrictive superpowers

The Threat: The Wunderkinder ProjectThe comedy turns into a high-stakes thriller when Dr. Ha Won-do returns to town. Decades earlier, he experimented on dozens of orphaned children to unlock human potential and discover the secret to eternal life

The survivors of those old experiments became superpowered enforcers, but their gifts came with a fatal catch: using their powers slowly destroys their bodies. To stop his dying enforcers from turning on him, Dr. Won-do hunts for a mythical biological specimen known as the "Child of Eternity". This unique person possesses perfect, uncorrupted immortality and holds the cure to the laboratory's fatal side effects

Team WONDERfools AssemblesAs Dr. Won-do's loyal test subjects begin terrorizing Haeseong City and abducting locals, the three clumsy heroes are thrust into the crosshairs. They form an alliance with Lee Un-jeong, a rigid civil servant from Seoul. Un-jeong is a former escapee of the Wunderkinder lab who has spent his entire life hiding his telekinetic powers.Together, this highly dysfunctional team must look past their personal flaws, learn how to trigger their absurd abilities, and stop Dr. Won-do's ultimate endgame before the clock strikes midnight on New Year's Eve

The Main Misfit Heroes

• Eun Chae-ni (played by Park Eun-bin): A 27-year-old known as Haeseong City's biggest trainwreck.

She gains teleportation (triggered by a high heart rate) and immortality. [1, 2]

• Son Gyeong-hun (played by Choi Dae-hoon): A well-meaning but pathetic husband and City Hall's master of filing complaints. Exposed to the dump's runoff, he gains a comically restrictive power: sticky hands. Whenever he tells a lie, his hands fuse to whatever he is touching until he tells the truth. [1, 2]

• Kang Ro-bin (played by Im Seong-jae): Chae-ni’s only friend and a timid kitchen worker at her grandmother's restaurant. He develops conditional super-strength and near-invulnerability, but the power only triggers when his feelings get hurt or he is insulted
