Underground (Season 1)

Underground (Yeraltı, 2026) is a Turkish action drama you can watch online on iFILM, directed by Murat Öztürk and starring Deniz Can Aktaş and Uraz Kaygılaroğlu.

Haydar Ali exacts revenge for his family's murder and lands in prison. Intelligence services find him useful: Turkey's most powerful criminal cartel runs its operation from inside, and Haydar is exactly the kind of man who can earn its boss's trust. He does — over three years of close quarters and shared risk. The day he walks free, that same boss turns out to be married to the one woman Haydar never managed to let go.

The series sets up a genuine bind: the ally and the obstacle are the same person. That makes it harder to root for a clean resolution — and harder to stop watching. Stream Underground (2026) online on iFILM.
