Detention Field Trip

Seven sixteen year old students get given detention. The school is sick of the same students who keep on getting detention day after day. So the Headmistress decides that the Janitor and the Mr Sage are to take the students on a one week detention to a city called Lashville to help rebuild the abandoned city. The journey is eight hours long and on a crumbly road has been barely ridden on. As they are four hours in, they get stopped by a body laying on the road. The janitor goes out to see if the body is okay, only to find that the body was not a helpless victim but a predator waiting for it's prey.

All in all, it's a horror story and their will be five victims and four survivors. Once the victims die, they turn into whatever killed them and all of the victims and 'dead bodies' that they find on the way are out to kill the survivors. Can they survivors get back to their school, or will they turn out like their other school mates?
