Julian Gilbey directs Melissa George, Ed Speleers and Sean Harris in this thriller where a group of mountaineers find themselves pursued by killers.
A gripping first hour, full of twists and lethal wilderness set pieces, gives way to a slightly more standard gangster shoot-out in the end. The grimly achieved sense of isolation and ambitious scale is sacrificed for shooters and hardboiled dialogue. Classy scream queen Melissa George and brittle Sean Harris are dab hands at this malarkey and fulfil their roles with an effortless quality. A diverting thriller.
