Erik Winter joins forces with his British counterparts after a series of brutal murders of young men in London and his own city of Gothenburg. The killer, dubbed Hitchcock, appears to have filmed the butchery, as evidenced by traces of a tripod stand in the victims' blood.

The trail naturally leads into the seamy world of snuff films, but the big break comes from a burglar who noticed some blood-stained clothing in an apartment he broke into.
