Dr. Brain (Season 1)

Dr. Brain (2021) is the Apple TV+ Korean sci-fi mystery you can watch online on iFILM. It comes from director Kim Jee-woon, the filmmaker behind I Saw the Devil, and stars Lee Sun-kyun of Parasite as a man who reads brains better than he reads people.

Neuroscientist Koh Se-won has never been able to feel what others feel. When tragedy tears through his family, he turns his own "brain sync" technology on himself, wiring his mind to the dead so he can replay their final memories from the inside. Every connection pulls back one shred of the truth — and leaves behind someone else's fear, grief and habits clinging to him. The line between investigating and being possessed thins with each sync.

Across six episodes, adapted from the webtoon by Hongjacga, this was Apple TV+'s first Korean original. Its real edge is Kim Jee-woon's cold, clinical control: not a cozy whodunit but a slow descent into borrowed heads where no memory can be trusted. Made for viewers who like their science fiction laced with horror. Stream every episode of Dr. Brain online on iFILM.
