Phi (Seasons 1–2)

Phi (Fi, 2017) is a Turkish psychological drama you can watch online on iFILM. Ozan Güven plays Can Manay — a celebrity psychologist with a TV show, a packed lecture schedule, and a reputation for reading people with clinical precision. One accidental look at Duru, a young dancer, and all that composure evaporates.

What follows isn't a courtship. Can buys the house next to hers. He engineers situations to get close to her. He studies her routines, dismantles her relationship with musician boyfriend Deniz (Mehmet Günsür) from the inside — all while Duru (Serenay Sarıkaya) has no idea of the extent of it. Surrounding this obsession: a student named Bilge who gets drawn into Can's world, a journalist building an exposé, and others who end up changed by proximity to someone this unhinged and this brilliant.

Directed by Mert Baykal and based on the novel by Didem Madak, the series is most effective as a portrait of a man who understands the human mind theoretically — and completely fails to govern his own. Stream Phi (2017) online on iFILM.
