Derek heads to a scrapyard to find a retired tow truck he can use around the shop. But this 1979 Dodge D300 has had a hard life and proves reluctant to go anywhere. Derek will have to hotwire the entire electrical system if he has any hope of making it home.

Derek returns to the shop where he apprenticed as a teenager, and to a 1979 Chevrolet K5 Blazer that's been sitting for over 20 years. He teams up with his brother Sean to reassemble this parts truck into a full-on trail machine to tackle the Black Hills of South Dakota. Along the way, they learn from Derek's old mentor why this truck sat forgotten for so many years.
