Hwayi: A Monster Boy

In a remote forest, a notorious five-member crime organization lives together on a deserted farm, bound by loyalty and fear rather than by law. The group is built around Seok-tae [Kim Yun-seok], the cold yet magnetic leader, with Ki-tae [Cho Jin-woong], a driving expert who speaks with a stammer, Jin-seong [Jang Hyun-sung], an ideal planner, Beom-soo [Park Hae-jun], a skilled gunslinger, and Dong-beom [Kim Sung-kyun], a disciplined martial artist. Their world is rocked when, as part of a blackmailing scheme that goes awry, an infant is left in their care. That baby grows into Hwa-yi, now a boy who lives as the son of these five fathers, and whose upbringing is anything but ordinary.

Hwa-yi, a child raised in close contact with crime, is taught by his fathers rather than sent to school. He absorbs a hard-won curriculum: driving, tactical planning, marksmanship, and martial arts. The household is an unusual school where every skill is learned through necessity and fear, and where affection is scarce but the bond between the boy and his guardians is intense. The boy named Hwa-yi, Yeo Jin-goo, grows into someone who can truly blend into their world, even as he secretly longs for a normal life that seems forever out of reach.

As the gang plots another crime, Hwa-yi is pulled into the plan for the first time. The operation spirals, and in the heat of the moment he shoots, his fingers shaking at first but then steadying with a sudden, almost possessed certainty. When he examines the image found on the man he has killed—a photo of a child—he realizes, with a shock that shards his sense of belonging, that the man is his real father. From that revelation, a burning resolve takes hold: Hwa-yi vows revenge on the fathers who raised him, using every devious skill they taught him to set his plan in motion.

Driven by vengeance, Hwa-yi begins by killing one of his five fathers. The others pursue him, but he manages to stay one step ahead. He lures the remaining men to Sungji Cement Factory, and a brutal clash unfolds as a rival gang arrives just before them. From a high vantage point, Hwa-yi begins to snip at the adversaries, sparing no one as the bloodletting erupts. When the dust settles, only Seok-tae and Hwa-yi remain standing.

Seok-tae heads to the hospital where Hwa-yi’s mother lies, and Hwa-yi follows in his wake. There, Seok-tae reveals the full story—from the orphanage to the kidnapping—laying bare the origins of the nightmare. The revelation is devastating, and Seok-tae ends up killing Hwa-yi’s mother in front of him. By the time Hwa-yi arrives at the hospital, it is too late to save her, and the boy must confront the man who raised him in a world of crime. Back at home, a tense confrontation with Seok-tae unfolds, with a detective dedicated to bringing the gang to account also present.

A violent standoff follows when Seok-tae destroys the detective, but Hwa-yi does not relent. In the final, brutal turn of events, Hwa-yi kills Seok-tae and steps away from the violence that defined his life for so long. The film closes on a stark, ruthless image: Hwa-yi, now a master of the skills taught him by his fathers, snipes the CEO of the rival gang, Moon Sung-keun, and then melts into the crowded streets, leaving his future—and his past—behind.
