Sweet Home 3 Full Episode English Subtitles
1. A World on the Brink
Season 3 of Sweet Home opens with a haunting aerial shot of Seoul swallowed by mutated forests, collapsed buildings, and drifting monster spores. Humanity has retreated into fortified settlement zones. Cha Hyun-Su, now an unstable but powerful half-monster, wanders through the outskirts like a ghost—neither enemy nor ally.
Hyun-Su wakes in a deserted school gym, his body covered in cracked scales. He stares into a broken mirror.
Hyun-Su (ENG SUB): “Am I still human… or just pretending to be one?”
His memories are fragmented—Song Kang’s character is fighting something deeper than monsters: the monster inside himself.

2. The Human Resistance Grows Desperate
Inside the Unified Shelter District 11, survivors gather under the leadership of Seo Yi-Kyung and the military remnants. Food supplies are scarce, and monster attacks are increasing. Tension runs high as rumors spread about a new mutation wave.
Yi-Kyung interrogates a captured creature—once human, now half-transformed. It speaks in broken words, trying to warn her.
Creature (ENG SUB): “He… he is coming… the one who chooses… who survives…”
Yi-Kyung’s eyes widen. A new Alpha monster is evolving—one beyond their worst fears.
3. Hyun-Su Returns
Hyun-Su appears at the District 11 gate, his silhouette causing panic. Soldiers aim their rifles, but Yi-Kyung steps forward.
Yi-Kyung (ENG SUB): “Lower your weapons! If he wanted to kill us, he would have already.”
Hyun-Su collapses from exhaustion. When he wakes in the infirmary, he sees Eun-Yu sitting beside him. She hides her relief behind her usual coldness.
Eun-Yu (ENG SUB): “You disappeared for months. Don’t expect a welcome party.”
Hyun-Su smiles faintly. Her presence grounds his fading humanity.
4. A New Threat Emerges
The peaceful moment shatters as a monstrous roar echoes through the shelter walls. A gigantic creature—part humanoid, part insect—bursts from underground. It crawls with impossible speed and impales walls with spear-like limbs.
Hyun-Su’s eyes darken. The monster within him awakens.
Hyun-Su (ENG SUB): “Stay behind me. I’ll handle this.”
He charges, transforming mid-leap. His back erupts with black tendrils, his face shifts, and his strength doubles. The fight is brutal—tendrils slashing, concrete exploding, soldiers firing.
Yi-Kyung realizes in horror:
Yi-Kyung (ENG SUB): “It’s not here by accident. It was hunting Hyun-Su.”
5. The Monster Evolution
After the battle, survivors examine the creature’s remains. Scientists discover a horrifying pattern: monsters are evolving with purpose. The new Alpha monster isn’t just powerful—it’s intelligent, strategic, and capable of controlling lesser monsters.
A chilling message is found burned into the ground near the shelter:
“HYUN-SU BELONGS TO US.”
Eun-Yu confronts him that night.
Eun-Yu (ENG SUB): “They’re after you. Why?”
Hyun-Su: “Because I’m like them… and like you.”
Eun-Yu: “I’m nothing like them.”
Hyun-Su: “You’re stronger than you think.”
Their bittersweet tension grows as the world collapses around them.
6. Yi-Kyung’s Search for Her Daughter
Yi-Kyung is still haunted by the loss of her child, who was taken by monster forces. She receives a mysterious recording: a blurry hologram of a young girl in a lab coat calling out:
“Mom… please find me…”
Yi-Kyung is convinced her daughter is alive—and important to the monsters’ evolution.
She prepares a dangerous expedition to the abandoned research complex known as Facility Zero, rumored to be the birthplace of the first mutations.
Yi-Kyung (ENG SUB): “Hyun-Su. I need your strength. Come with me.”
Hyun-Su: “If we go there… I might not come back human.”
But he agrees.
7. The Dark Truth of Facility Zero
The team—Hyun-Su, Yi-Kyung, Eun-Yu, and a small squad—ventures into Facility Zero. The corridors are littered with dried husks of earlier monsters. A strange living fungus pulses on the walls, whispering like a heartbeat.
Eun-Yu shivers.
Eun-Yu (ENG SUB): “This place feels alive.”
Hyun-Su: “It is.”
They find video logs revealing that humans once attempted to weaponize monster evolution. Experiments on children—immune, adaptable, gifted—were central to the project.
Yi-Kyung’s daughter was experimented on to accelerate human-monster coexistence. She wasn’t just taken—she was created.
8. The Alpha Monster Reveals Itself
The ground trembles. A massive shadow descends like a god emerging from darkness.
The Alpha monster stands before them—tall, humanoid, plated like armor, with glowing red lines across its chest.
It speaks clearly.
Alpha Monster (ENG SUB): “Hyun-Su… brother… come home.”
Hyun-Su steps back, horrified.
Hyun-Su: “I’m nothing like you.”
Alpha Monster: “You are our future. They will never accept you.”
Eun-Yu grabs his arm.
Eun-Yu (ENG SUB): “Don’t listen. You’re still you.”
The monster snarls, launching a devastating attack. Facility Zero collapses as Hyun-Su fights with all his strength, but he is outmatched. Every blow sends him flying, bones cracking and healing instantly.
Yi-Kyung finds her daughter inside a glass containment pod, alive but changed—her eyes glow faintly, like Hyun-Su’s.

9. A Sacrifice in the Shadows
The Alpha monster prepares to kill Eun-Yu. Hyun-Su unleashes his full monstrous form—dark wings, skeletal tendrils, and flaming scars.
The screen fills with chaos as he roars:
Hyun-Su (ENG SUB): “DON’T TOUCH HER!”
His transformation shakes the facility. For a moment, he is more monster than human.
Hyun-Su defeats the Alpha with a brutal strike, but not before the monster whispers:
“The world will kneel… to what you become.”
10. The Ending – A World Afraid of Its Savior
Back at District 11, survivors cheer Yi-Kyung’s return with her daughter. But when they see Hyun-Su’s monstrous final form still clinging to him, fear replaces gratitude.
Soldiers point their weapons again.
Eun-Yu stands between them.
Eun-Yu (ENG SUB): “If you shoot him… you’ll lose the only one who can save us.”
Hyun-Su’s voice breaks as he looks at the terrified survivors:
Hyun-Su (ENG SUB): “Maybe… I don’t belong here anymore.”
He walks away from the shelter, leaving Eun-Yu in tears.
The final shot shows Hyun-Su standing atop a ruined skyscraper, watching the horizon as thousands of monsters gather—waiting for a leader.
Hyun-Su (ENG SUB): “If this is my destiny… then I’ll choose what kind of monster I become.”
Fade to black.
