The gruelling training, clandestine mission and sacrifice is familiar Boy's Own stuff but the lack of a decent budget really hurts the film.

Dyer has forged a career around screen violence which can leave a very unpleasant aftertaste. But this is a relatively conventional Second World War story about seizing Nazi radar technology from occupied Norway and he's all the better for it.

This film's shoestring budget is just far too apparent, making it impossible to take seriously. But it has its moments.

Bean and Danny Dyer butt heads in an engaging manner, and the icy locations add an atmospheric backdrop.
