Detective Winter sneaks into a criminal's apartment looking for evidence, but she is surprised by the creep. He orders her to strip naked, and then assaults her in a very rough way, groping her, inspecting her genitals. He ties her up in a hogtie, gags her, and begins worshipping her feet while she squirms helpless and disgusted.
After that, he changes the bondage and connects the hogtie around her throat, so that Winter has to struggle to prevent strangling herself... But, in the end, she will have to give up and die, after the killer has been watching her agonizing for some time.
