The performances from the young cast are a tad bland, but director Jon Hewitt infuses his low-budget genre jolter with just enough menace as it powers towards an effective, if predictable, climax.

Unfortunately, after a strong first half, the film degenerates into some messily unconvincing blood-letting which might attract devotees of the genre but which is disappointingly conventional given what's come before.

When Edgerton's killer begins to toy with (Sebastian Gregory's) Mark, it's like watching a cat play with a mouse - it's sad but you don't really care. Let the cat have his fun...

Cleverly twisted, gut-wrenching Aussie thriller.
