Overview: In the north east of England, Alpha recovery ops Kevin and Ian battle the snow and ice to rescue a stricken fuel tanker that's slipped off a frozen track while making a delivery. With nowhere to turn and limited space they must perform a tricky reverse winch pull using hundreds of metres of line. They're relying on a tree as an anchor point and the power of their 4x4 road rescuer. It's a risky manoeuvre, if they get it wrong the cable could snap causing carnage.
