Inhuman Kiss (2019) – Full Plot Summary & Ending Explained

Read the complete plot breakdown of Inhuman Kiss (2019), including all key story events, major twists, and the ending explained in detail. Discover what really happened—and what it all means.

The film opens in a quiet forest where four children Jerd, Sapol Assawamunkong, Sai, Phantira Pipityakorn, Noi, Oabnithi Wiwattanawarang, and Ting, Darina Boonchu wander among the trees, drawn to a local legend about a protective spirit known as a krasue that guards the woods. The mood is curious and almost folkloric as Sai dares to peek inside a long-forgotten box, where she encounters something otherworldly, though the scene simply ends with a quick shift to years later.

Years slip by and the story follows the same four friends as teenagers in a country torn by World War II. Sai works as a nurse in a local hospital, moving through crowded wards to tend wounded soldiers, a task that Jerd quietly admires from afar as he harbors a crush on her. Meanwhile Noi has traveled to Bangkok to continue his medical training, and Ting remains nearby, linking the old forest to the new, modern world creeping into their village. The war time mood adds a sense of urgency and danger to every choice they make.

A reunion takes shape when Sai meets Noi again in the forest, and old affections flare into a rekindled romance. It’s soon revealed that Noi and his tribe have traveled to Sai’s village with a dangerous mission: to hunt a krasue. The tribe’s leader speaks of a brutal, ancient dynamic: a female krasue can seduce and transform a woman, while a male krasue (a krahang) endures a painful metamorphosis that often ends with his guts being devoured—an ominous preface to the danger Sai might face.

Sai begins to notice disturbing signs—blood stains on her bed that grow darker with each passing night. One night she screams in pain, and the horrifying moment arrives: her head detaches from her body and soars above, revealing that she has become a krasue. In the night she roams to hunt, catching meat to sustain herself and then returning to her human form by dawn. Noi, witnessing this, becomes a quiet beacon of support, helping her obtain meat and drawing them closer, while Sai increasingly withdraws from Jerd.

The story deepens with a painful revelation: Jerd had suspected Sai’s true nature all along and had joined the krasue-hunting tribe to misdirect them. When the tribe’s leader—who is also a krahang—learns of Jerd’s disloyalty, he brutally transforms Jerd into a grotesque krahang. Sai visits him, and he begs her not to leave, revealing that her plan to run away with Noi to Bangkok would have torn them apart in another life as well.

To expose the truth to the village, Sai’s father takes her to a mass movie theater near the village border, a public display meant to prove that the rumors of Sai’s krasue-ness are unfounded. But a monk’s guiding words, delivered by Noi’s mentor, recount an ancient tale: a krasue who fell in love with a human and bore his child was killed by a furious krahang—an old tragedy suggesting that lovers of different kinds are doomed to conflict. The tale foreshadows a grim possibility for Sai and Jerd’s futures and hints at the fragility of their fragile bond.

The village’s fear erupts when Sai fully transforms, and villagers chase her with weapons. Noi pleads with Jerd not to kill the friend he once trusted, but violence erupts around them. Jerd dies at the hands of angry villagers, and the monk confronts the threat with a decisive act that ends the pursuit. In a wrenching twist, it’s revealed that the krasue who changed Sai is actually Nual, the wife of the monk who had helped Noi all along. This confession reframes the entire arc of loyalty and guilt, as the monk Makorn Supinacharoen—playing Monk Pai—had hidden the stakes by protecting Sai and orchestrating a painful cure to a husband’s remorse.

Sai and Noi flee toward the river, hoping to reach Bangkok, but the journey proves futile as Sai’s body has already been destroyed by the villagers’ fear and force. In a final, devastating moment, Sai is killed by a gunshot from Jerd’s parents, leaving Noi to grieve a love that burned bright yet could not survive the village’s endless suspicions and the weight of ancient legends.

In the end, the film leaves behind a quiet, haunting reflection on love, transformation, and the old tales that linger in the shadows of a country trying to heal from war. The characters—Jerd, Sai, Noi, Ting, Nual, Tat, and the monk—each carry a piece of that legend, and their intertwined fates offer a somber meditation on fate, loyalty, and the price of fear.
