Directed by Xavier Beauvois, Of Gods and Men won the Grand Prix at this year's Cannes Film Festival. Set in the mountains of North Africa, it's loosely based on a true story about eight Christian monks and the difficulties they face when a group of Croatian workers are killed by Islamic fundamentalists. The monks have lived peacefully in the area for years but now they have a stark choice to make - accept help from a corrupt military, pack up and leave, or face almost certain death.
