So a group of Stone Age wanderers are searching the bleak wilderness for a new home when they begin to suspect that they are being stalked. Noises in the woods unsettle them, but they see nothing. Suddenly, though, one of their number is taken and the leader "Adem" (Chuku Modu) must make some difficult choices to ensure the survival of both his son and of his pregnant wife. The denseness of the Scottish forestry along with some creative use of light, shadow and audio goes some way to keep the film interesting but the plot itself is really weak and the actors - perfect teeth, skin, leather clothing that wouldn't look out of place at a gay pride gathering - all deprive the thing of any sense of menace or grittiness. It's difficult to watch without thinking the production caravan is just three feet out of shot! The redeeming feature may be an impressibly natural performance from Safia Oakley-Green ("Beyah") but I'm afraid for the most part, I struggled to remain engaged and the ending, well that was just rushed and a little disappointing too. I would still suggest you watch it, if you get the opportunity - but on the television is fine and don't expect to be scared.
