Exploring the events which led to the murders of Paul Longworth and Albert Alfonso's in their west London flat.

While Albert is doing a lifeguard shift in a nearby gym, Columbian porn performer Yostin Mosquera searches the internet for, “Where on the head is a knock fatal?”. Then he takes a hammer to the skull of Paul Longworth.

Once dead, Mosquera puts Paul’s body in storage space under the bed. When Albert returns from work, the pair start filming an extreme sex session.

It turns into a brutal attack by Mosquera on Albert – captured on four cameras in the bedroom.
