The film stars David Oakes, Tom Kane, Jennie Jacques, Liam Boyle, Jack Gordon, Florence Hall and Alexander Vlahos.

After trying to find a way into the building, they are interrupted by the groundsman, Woodbridge (David Sterne), who tells them the correct address; a small shack half a mile down the beaten track, in the forest behind the mansion.

They walk through the woods to the shack, where they are welcomed by a mysterious, handsome man named Justin (David Oakes), who reveals himself to be the elder brother of Felix.

With Justin having swapped the position of the jars, Paul unintentionally chooses the one containing acid, and Chris chokes to death, bleeding heavily from his mouth.

Before Justin can continue, the group is interrupted by an intruder, knocking at the door (who is revealed to be Luke's drug-dealer friend, Jonesy (Jason Maza), who followed them to the party).

However, after convincing him to help her snort cocaine while she is tied up, Eleanor bites off Luke's little finger, sending him flying backwards and impaling himself in the back of the head on a tool on the floor, killing him.

The three break out into a brawl, wherein Eleanor manages to both shoot Justin in the shoulder, and severely burn him by smashing the jar of battery acid over his head.

Eleanor reveals that it was never really the postcard that drove Felix to suicide, but in fact, a video she had blackmailed him with in exchange for money to help save her father's failing business.

It has its bloody horror film moments, but director Robert Heath wisely puts equal emphasis on the psychology of its hostage situation".
