The snow comes in hard, tangling and mangling traffic in Donner Pass. Sam from "Nyack Towing" must winch up a young driver's pick-up which has plunged down a steep incline and slammed into a tree. Becky and Edgar from "Dependable Tow" struggle to extract a big rig loaded with hay from a ditch far below the highway. Will of "Running Bear" rescues an SUV which has hit black ice on I-80 and flipped. Nearly out of gas, Will works fast to upright the SUV while the CHP watches him like a hawk.
