Six office workers are sweltering through a team building exercise in a remote Spanish national park when they see a man plummet out of the empty blue sky to Earth. Examining the body they find a haul of diamonds twinkling among the blood, rocks and shrubs. There is nobody else around for miles. The sun is high. The black-clad figure is dead. What the six choose to do next will decide their fates and that of the diamonds owners, those keen to track the stones down and even that of the body in the dust.
