Gach geamhradh, air Prìomh-rathad a h-Ochdad ann an California, faisg air Bealach Donner agus baile Truckee, tha trì sgiobaidhean de thobhadairean a' cur am beatha ann an cunnart gus draibhearan ann an èiginn a shàbhaladh. Seo fear dhe na rathaidean as cunnartaiche ann an Aimearaga, agus tha am program seo a' leantainn dhraibhearan a dh'fhaodas faighinn suas ri
còig-deug calla san latha. Bidh aca ri a dhol a-mach ann an cabhadh agus ann an stoirmean reòithte, agus còmhla ri sneachd is cabhadh, tha leathadan cas, carbadan ann an craobhan, agus fiù 's naoidhean gu bhith air a bhreith.

Tha an fharpais eadar Sam Jackson agus Eddie Farrow a' teasachadh. Tha eagal a' bhàis a th' aig Brandon Goulet a' tighinn gu math dlùth air, nuair a thèab carbad bualadh ann air an rathad. Tha tachartasan duilich ann an eachdraidh Becky Norman a' tighinn dlùth oirre nuair a fhuair i calla gu tubaist motorbaidhg mairbhteach. Agus, thall aig Running Bear, tha Will Slade a' cur iongnadh air a h-uile duine leis an naidheachd aige.

Every treacherous winter on California's US Interstate 80, near Donner Pass and the small town of Truckee, three teams of hardcore tow truck drivers risk their lives rescuing stranded motorists across one of the most dangerous roads in America. It is all about high risk and high reward, with each driver responding to as many as fifteen calls a day, sending them out in blinding blizzards and ice storms in the dead of night.

The competitive rivalry between Sam Jackson and Eddie Farrows heats up. Brandon Goulet's fear of death becomes very real when he's almost hit on the highway. Becky Norman's tragic past comes back to haunt her when she is called to the scene of a deadly motorcycle accident. Meanwhile, at Running Bear, Will Slade makes a stunning announcement. Show less
