Preparing for her wedding, Kübra gets possessed by unknown livings. To cure Kübra, a psychiatrist, Ebru, gets on way. Ebru is also an old friend of Kübra. Ebru would work together with an exorcist to save Kübra. Just when things seemed to be going well, everything start going horribly wrong.

Almost 2 hours plus, but the ending is fucking amazing and there have been sequels to the movies which almost is related to the theme of Djinn an ancient demon something, and i have almost seen all of the works of the director.

If you love gore along with great drama, don't miss his works,
