Save the Green Planet!

Byeong-gu is a whimsical yet tormented man who believes that extraterrestrial beings from Andromeda PK 45 are about to invade Earth. He feels a heavy burden as he sees himself as the sole protector of humanity, which sets the stage for his desperate actions.

Byeong-gu's playful circus performer girlfriend, Su-ni, becomes determined to support him despite his eccentric beliefs. Their relationship is marked by laughter yet overshadowed by Byeong-gu's paranoia about the impending alien threat.

Convinced that Kang Man-shik, a high-ranking pharmaceutical executive, is an alien in disguise, Byeong-gu devises a desperate plan to kidnap him. This decision marks the beginning of a series of horrific events that spiral out of control.

Byeong-gu and Su-ni successfully imprison Man-shik in Byeong-gu's basement workshop, where he intends to extract vital information. The basement becomes a site of torment, illustrating Byeong-gu's disturbed mind and his belief in extraterrestrial conspiracies.

As Byeong-gu tortures Man-shik with painful methods to disrupt his supposed alien communication, he faces a dark revelation. It becomes evident that Byeong-gu’s mother was a victim of a pharmaceutical trial run by Man-shik's company, deepening his need for revenge.

A detective arrives to investigate Man-shik's sudden disappearance, creating tension as Byeong-gu attempts to cover his tracks. The detective is initially oblivious to the chaos unfolding, but his instincts alert him to the disturbing atmosphere surrounding Byeong-gu.

While exiting, the detective notices Byeong-gu's dog, named Earth, gnawing on remnants of previous victims. This grim discovery prompts an uneasy feeling in the detective, foreshadowing the violent encounter that awaits him.

As the investigation unfolds, the detective meets a gruesome end at the paws of Byeong-gu's pet bees. His death marks a pivotal point in the narrative, escalating the horror and chaos embodied by Byeong-gu's mental state.

In a moment of manipulative ingenuity, Man-shik leads Byeong-gu to believe that a bottle of benzene in his car could cure his mother’s comatose state. This information drives Byeong-gu into a frantic rush to the hospital, leaving Man-shik a chance to escape.

Alone in the chaotic workshop, Man-shik discovers unsettling evidence of Byeong-gu's chilling experiments. He uncovers horrific photographs and notebooks filled with Byeong-gu's violent history, providing chilling insights into his fractured psyche.

The situation escalates when the detective's partner finds a frantic Man-shik just as Byeong-gu arrives home in a blind rage. A tumultuous struggle ensues, revealing the depths of Byeong-gu’s madness and his desperate attempts to shield his twisted reality.

In a surprising twist, Man-shik claims to be an alien, spinning a fantastical tale about saving humanity from a destructive gene. This bizarre confession is a strategic delay, as he desperately seeks to bide time while plotting his escape.

Byeong-gu rushes to the pharmaceutical factory, desperate to confront Man-shik. It is here that the situation culminates in a dramatic showdown, revealing Byeong-gu's fate as he battles varying forces of chaos and despair.

In a tragic conclusion, Byeong-gu is brutally beaten, and law enforcement arrives, only to shoot him as he lies bloodied and dying. His last words reflect a heartbreaking realization of his perceived failure in saving the world he desperately wished to protect.

In a shocking twist, it is revealed that the aliens are indeed real and they abduct Man-shik, who is unveiled as the alien king. Disappointed by humanity's cruelty, the aliens make the fateful decision to obliterate Earth, marking the end of Byeong-gu's tragic story.
