Hi-Five Korean Ending Explained And Movie Summary: Is Young-Chun Defeated?

With DC’s Superman soaring back into the global spotlight, it’s hard to imagine there’s room for superhero stories beyond capes and icons. Enter Kang Hyeong-cheol’s Hi-Five, a wildly original take that trades fame for freshness, serving up a quirky origin story and a cast whose sharp comedic timing makes the genre feel a lot fresher. Drawing inspiration from different human organs, the superpowers granted to our heroes, and even the villain—aren’t wildly far-fetched. But it’s the director’s clever execution and imaginative storytelling that elevate this concept into something truly engaging and fun. 

Spoilers Ahead

What happens in the movie?

Park Wan-seo undergoes a heart transplant from a mysterious donor, marking the beginning of something far stranger than recovery. Her overprotective father, Park Jong-min, still haunted by the loss of his wife to a heart attack, pleads with Wan-seo to give up taekwondo and avoid anything that might strain her heart. To him, she’s all he has left. Still longing for a sense of normalcy, Wan-seo begins sneaking out to run and play like other kids her age. Her illness had forced her to repeat a school year, leaving her socially adrift and aching to reconnect. But the moment she runs again, she realizes something’s changed. She blazes past bikes, outpaces cars, and before she knows it, her feet leave the ground. She’s not just fast; she’s flying. Soon, she meets Park Ji-sung, who has undergone a lung transplant that grants him the ability to unleash powerful blasts of air, blowing away anything in his path. They soon realize that five major organs that can be transplanted—the heart, lungs, liver, kidneys, and eyes—and that each one may have passed on a unique power. Determined to uncover the truth, they set out to find the three others who received these mysterious transplants. They soon find Kim Sun-nyeo, a fresh food delivery agent who’s had a kidney transplant. Though she doesn’t show any obvious signs of superpowers, her compassion draws them in. Together, the three eventually encounter Hwang Ki-dong, the man who received the cornea transplant, bringing them one step closer to completing the mysterious puzzle. Hwang Ki-dong, who got the cornea transplant, turns out to have a pretty wild ability: he can control electric and magnetic waves, and with just a snap of his fingers, lights flicker, phones glitch, and machines bend to his will. Meanwhile, a shady cult leader and self-proclaimed godman named Young-Chun also went through a transplant, and received a terrifying power as a result. He can suck the life out of people, draining their energy to make himself younger. Each of the people with a power has a unique tattoo of their own, representing their ability. 

How do the good guys form a team?

Young-Chun is a powerful and influential figure in the country, with factories under his control that operate without proper safety protocols or equipment. When the workers finally speak up, their manager, Huh Yak-sun, sides with them and tries to take their concerns to higher officials, but no one listens. That’s when we discover Yak-sun has a secret of his own. When a worker is severely injured in an accident, Yak-sun steps in and heals him, revealing a hidden superpower. But the cost is heavy; each time he heals someone, it drains him painfully, and the only way to ease that agony is by chugging down a lot of water. Meanwhile, the four others fail to bond as a team, and Ji-sung and Ki-dong beef with each other over every little issue. But when Ki-dong is abducted by a few guys working in a casino, Ji-sung sneezes real hard to set him free. A chase sequence follows, where Wan-seo, with her ability to sprint, pushes a cart with the rest of them. The casino guys follow, along with men working for Young-Chun’s daughter, Choon-hwa. Even though they manage to slip away, Choon-hwa catches wind of their abilities. That’s when Ki-dong drops a little tea of his own; it turns out Ji-sung is a failed screenwriter who’s never written an original line in his life, always plagiarizing scripts and pretending they’re his. On top of that, he’s a full-time troll, constantly trashing films online without even watching them. The group splits apart, and Wan-seo lashes out at her father for constantly being paranoid over her. 

Why does Young-Chun abduct the group?

When one of Young-Chun’s factories actually catches fire, Wan-seo, Sun-nyeo, and Ji-sung rush to the spot to rescue people. Yak-sun finds a worker stuck behind a locked door, and he’s terrified that he can’t help him. Wan-seo comes in, trying to kick each door down, and just as she can’t do the same for the last door, Ki-dong comes whistling and snaps to open the door and let them rescue the worker. But all these antiques weren’t going to go unnoticed, and Young-Chun finds out about Yak-sun’s abilities. His daughter makes sure all of them are brought to them, and except for Wan-seo, they are kidnapped by his men. Young-Chun fails to absorb Yak-sun first, but he manages to put him through surgery and take his powers himself. He also makes his doctor extract Ki-dong’s cornea, permanently blinding him. 

How does Young-Chun show off his new avatar?

Much like Jesus Christ himself, Young-Chun promised his followers he’d return from the dead and lead them to heaven, this time in a brand-new vessel. Ironically, the task of honoring that promise now falls to his daughter, who spent most of her life just wishing he’d die already. And yet, here she is, orchestrating a spectacle for his so-called resurrection that looks more like a Super Bowl halftime show than a spiritual awakening. When Young-Chun finally makes his grand return after taking the powers from Ki-dong and Yak-sun, he doesn’t just resurrect; he rebrands. Looking like a K-pop romance hero fresh out of a fan fiction fever dream, he’s got the flawless skin, the slow-mo hair flip, and the kind of jawline that could split the ocean in half. The audience can’t believe that he’s the same person, and Young-Chun jumps across the stadium to crush the wall, which had a portrait of his older version. Then he starts performing miracles, like curing someone’s leprosy, fixing a kid’s asthma, and so on. The crowd goes wild, fully convinced their leader has finally tapped into some real-deal divine powers.

How does the Hi-Five defeat Young-Chun?

Wan-seo and her father, Jung-se, arrive at the arena where Young-Chun is busy playing God, basking in his self-made divinity. But he’s already one step ahead—he knows his enemies have come, and in true theatrical fashion, he even opens a door for them like it’s all part of the show. Meanwhile, our captive heroes manage to break free. And then, the main event: Wan-seo and Young-Chun clash in an over-the-top, hand-to-hand showdown straight out of a superhero blockbuster, but with more personal grudges and slightly less CGI. But Young-Chun proves to be too strong for Wan-seo to handle alone, and this is where we get to know about Sun-nyeo’s powers. Sun-nyeo has the ability to channel power through touch; by holding others’ hands, she can transfer their abilities between them or funnel everyone’s power into a single person. So after a good old effort to neutralize the villain for a bit, they finally try to give the powers back to Ki-dong and Yak-sun, but to their surprise, Young-Chun also joins the handholding session, hoping to take the powers back all for himself. He twists Wan-seo’s arm, forcing her to the ground in front of him. That’s when she finally cries out for her father, who’s been unconscious this whole time, only for Jung-se to come soaring in with a perfectly timed taekwondo kick that sends Young-Chun flying. But there was one last problem to fix for the heroes, and a big one. 

The high-voltage brawl triggers the collapse of Young-Chun’s massive statues, revealing hidden electrical transformers buried beneath them. As the entire arena begins to crumble, the God-worshipping crowd remains in a state of pure euphoria—cheering like it’s a spiritual rock concert, imitating the reaction straight out of The Simpsons. Ki-dong urges the gang to transfer their powers to him, believing he can absorb the surge and neutralize the threat of the exposed electrical transformers bursting. Ki-dong had a childhood trauma, where he once accidentally touched a small transformer and his friends ran away, leaving him alone. But this time, when Ki-dong looks back, he sees his new friends standing with him. Drawing strength from their presence, he manages to contain the chaos all on his own. Together, they send Young-Chun back to the main stage, slumped on his throne, old, defeated, and dying. 

In Hi-Five’s ending, the group finally find themselves fixed, and everyone gets their superpowers back, and the tattoos as well. After defeating their first big villain, they decide to name themselves the Hi-Five, since they’re five people, and well, I think it’s catchy too. So for anyone who’s willing to look beyond The Avengers and The Justice League, there’s a new superhero group in town for you.
