Want to enjoy some insomnia? Turkish horror film Baskin, the feature debut of director Can Evrenol, looks like it’s going to keep people awake for hours after it ends. At least judging from the official Toronto International Film Festival trailer, some of the most disturbing one minute and thirty seconds you’re likely to have this year. The film follows five cops working the graveyard shift who get called out to the middle of nowhere to investigate a disturbance. Sans backup, the policemen end up in a labyrinthine ruin that conceals the blood soaked den of a group of terrifying cultists that plunges them into a bloody world of violent madness.

XYZ Films executive produced and will handled North American sales, while The Salt Company is handling international. Baskin makes its world premiere this year at TIFF on September 11, with Evrenol in attendance, who is probably going to have to hug a lot of people who see it, at least me. I’m dying to see it, but you can judge for yourself – watch the trailer above.

TIFF 2015 happens September 10–20 in Toronto. This year’s event will see screenings of more than 300 films from over 60 countries.
