Horror Idea - Dead End

A family are travelling home from picking up their daughter from University. They live in a small remote countryside village; a road is closed due to unknown reasons that took place in the forest which the road takes you past. However, ignoring all the signs on the road and not listening to the warnings on the car radio they take the road. When they arrive at the woodland area, they find helpless survivors on the road using a flash light to flag people down. When they see this survivor they immediately get out of the car to help, when they do so they are surrounded by a group of zombie like creatures. When they try to leave, they discover they are locked out of the car and can’t get away, so run into the woodland. Then the zombie killers find them, hunting them down to their bloody death!
