Paul Teutul Sr. and his sons, Paul Jr. and Mikey are back along with old and new faces, as Orange County Choppers expands to meet the demand for the sickest custom motorcycles around. Follow this creative, yet explosive team as they battle tight deadlines (and each other!) to come up with innovative ways to take motorcycle design and fabrication to the next level.

Paul Sr. gets to the getting and fabricates a custom chopper to honour America's forgotten heroes, those missing in action or prisoners of war.

The OCC crew decide to visit The National Vietnam Veterans Memorial in Washington, D.C. known simply as 'The Wall'. Everyone is moved by the trip and they take a rubbing of the names to incorporate into the paintwork.

When the project falls behind schedule due to last minute design changes and setbacks, the strain Paul Sr. is under starts to show but the OCC crew rally together to complete the heartfelt tribute in time for its public debut. When it comes to the unveiling Paul Sr. is nervous but he needn’t have worried judging by the misty-eyed reception from the Vietnam vets present.
