Parasyte: The Grey (Season 1)

Parasyte: The Grey (2024) is a Korean sci-fi action series you can watch online on iFILM. Directed by Yeon Sang-ho — the filmmaker behind Train to Busan — this six-episode Netflix original adapts Hitoshi Iwaaki's manga for a Korean setting, with a new story and new characters.

Alien parasites are entering human hosts, overriding their brains, and hunting in plain sight. Su-in should have been another victim. The parasite reached her — but couldn't complete the takeover. She survived with a second consciousness now sharing her body, and a very uneasy truce between them. Jun So-nee plays Su-in, navigating a world where anyone around her could be a parasite wearing a human face. Koo Kyo-hwan is the detective trying to track what's happening before the body count grows.

Released in April 2024, the series topped Netflix charts across multiple countries in its first week. The tone is closer to body-horror thriller than typical K-drama — tense, violent, and unsettling. Stream Parasyte: The Grey online on iFILM.
