Traffic is choking Britain’s roads and trouble shooter Kris Murrin is on a mission to halt this. Her aim is simple: for just one day, Kris will try to persuade a town to leave their cars at home and go car-free.

Kris steps up a gear in the final stage of her campaign and heads to the city of Durham, where the council are raring to go, already providing a number of services to get the residents of Durham walking, cycling and using public transport. But after a bitter blow with Boston, will Kris be able to bounce back and get results?
