A 'leisurely drive' planned in honor of Radiator Springs’ town founder, Stanley, turns precarious as Baja pros descend on the town and challenge Lightning McQueen to an off-road race. Meanwhile, the townsfolk, led by a Stanley-costumed Mater, enjoy the planned 'leisurely drive' to retrace Stanley’s original frontier route. Thinking they’re on the same course, a wrong turn sends McQueen and the Baja pros on a treacherously wild bid for survival. The misunderstanding leaves the racing professionals in awe of the 'legend' of Stanley: the Original Off-Road Racer.
Unfortunately the movie The Radiator Springs 500½ is not yet available on HBO Max.
