In Northamptonshire, recovery specialist Jamie is called to the scene of a crash where a mangled car has been abandoned by its driver

In Northumbria, the pressure is on as specialist heavy recovery driver Michael tries to retrieve a lorry that has careered off the carriageway into a ditch. Meanwhile on a foggy and snow-covered A-road, Phil of Reading breakdown patrol tries to get a stranded driver up and running as traffic thunders by, while officers from Thames Valley Police recall a notorious Valentine's Day pile-up that involved 40 vehicles.
