Five Turkish police officers answer a call for backup, and find themselves inside an abandoned police station that is a portal to a strange and terrifying hell.

This is a visually striking film, bathed in red light, buckets of gore, and terrifying images glimpsed at the edge of the screen and lurking in the shadows. The Grand Guignol horrors on display are more than a little over the top, with manglings and mutilations and torture galore, and the story quickly becomes weirdly allegorical while also insanely bloody. It’s definitely nightmare fodder, but stunningly executed all the same.
