Opening scene: It's dark, theres blaring lights from police vehicles. You can hear the washed out sound of police sirens and people shouting. Everything is slowed down. You then can see the people jumping out the back of the camper van, one of them is clutching their stomach in pain with blood drooping down. Three people come out and into the helicopter. The helicopter flies off and a police officer walks into the camper van. He shines his light around, his light lands upon a body, he calls to another officer that they need to see this. 

This opening scene stops there and it goes back 2 weeks prier.
