Well done.
A young family named Sewell are planning to take a holiday abroad and with all the mod-cons of the day i.e a caravan they can go anywhere and have decided to travel abroad.
They are making their way to Dover from Birmingham, (no motorways or sat nav, just simple map directions.)
Unfortunately, they find some criminal in their caravan, named Dewar.
This man is a bad piece of work and he's just killed a night watchman so he's desperate to get away from the police who want to speak to him. The police are making stop and search road checks to find him. He has found a way of avoiding them.
