Circle (Season 1)

Circle: Two Worlds Connected (2017) is a South Korean sci-fi thriller you can watch online on iFILM, directed by Min Jin-gi. The story runs on two parallel timelines — 2017 and 2037 — and the gap between them is where all the answers are buried.

In 2007, a pair of student brothers and their father witness an alien landing. The extraterrestrial doesn't attack. Ten years later in 2017, Yeo Jin-goo plays one of the brothers trying to understand why everyone connected to that night is dying — and why he and his twin have disappeared from the record. Cut to 2037: the world has divided into Smart Earth, a society that suppresses crime by implanting emotion-regulating chips into citizens' brains, and Ordinary Earth, where no such order exists. The link between the alien contact of 2017 and the fractured world of 2037 is the spine of the whole plot.

Korean genre TV rarely attempts this kind of interlocking architecture. Both timelines are written to pay off independently before they converge. Stream Circle online on iFILM.
