After a telegraph pole truck gets stuck down a narrow country lane, Incident Manager Steve requires a very special bit of kit, The Unitrak: a custom built recovery vehicle, which runs on tracks to enable it to access areas other vehicles can't. Being totally unlike anything else to drive, it's a huge test for Steve's maneuvering skills negotiating a slippery and muddy field just to get to the truck. The difficulties don't end there, with winch apparatus having to be operated over a hedge and darkness descending, which means in the heart of rural Herefordshire, this complicated rescue must be executed by the light from the vehicles and torches alone.

Operator Daniel faces his first ever coach rescue job, after a 56 seater gets stranded on the biggest roundabout on the motorway network, on a junction between the M25 and A1(M). With four lanes reduced to two, traffic is relentless, giving Daniel terrifyingly little room in which to work. Right next to an active lane, he must try to remove the coach's half shaft, but with a very thorough paint job having seemingly secured the nuts around it extremely tightly, Daniel has a problem. He must solve it quickly, as there's huge pressure to get the closed lanes open again.

Near Newcastle, veteran operator Kevin comes across a septic tanker wedged in construction aggregate dolomite at the entrance to a building site. With expensive pumpwork on the truck's underbelly, Kevin must exercise supreme caution as this is a rescue which must not be rushed.
