Over the past year, Paul Sr. and Paul Jr. have taken steps toward mending their once fractured relationship. Faced with the challenges of a changing market and a need to build mind-blowing bikes, the Teutuls must push their limits on every signature build. Paul Sr. takes a risk at Orange County Choppers as he moves his bike designs in a different direction. However, he also jumps at an opportunity to go back to his roots, designing a throwback line of affordable motorcycles. Meanwhile, Paul Jr. - working to keep up with looming deadlines as he takes on new concepts and builds - challenges himself to build a streamlined bike for the MLB Network, all to impress his father who recommended him for the job.
