Find out where to watch on


There is something horribly wrong with the bodies found in the dark city streets. Some are mutilated while others have the Price equation (wΔz = Cov (w,z) = βwzVz) carved into their flesh. Detective Eddie Argo and his new partner Helen Westcott unearth the meaning of the odd equation and realise each victim is being offered a gruesome choice: kill your loved ones, or be killed. Before long it becomes clear that the perpetrator has suffered a similar fate and is now coping by seeking a way to solve this philosophical dilemma.

A review by John Chard

By John Chard

Altruistic Nightmare!

Bodies have started turning up with W∆Z carved into their skin, cops Eddie Argo (Stellan Skarsgård) and Helen Westcott (Melissa George) investigate and find something truly disturbing is afoot.

It's cut from the same cloth as Saw, Seven and to a degree Hostel, in that it's torture pornish in narrative essence, and aesthetically grim with its neo-noir greens and browns. Tom Shankland's movie is undeniably bleak, but sift through the blood and the grime and you find there's an intelligent film at work, one that opens up an uncomfortable can of worms about human nature.... read the rest.
