This documentary tells the story of an unsung hero and self-made man, David Abbott Jenkins, who, with almost superhuman stamina and boyish charm, set out to single-handedly break every existing land speed record on his beloved Bonneville Salt Flats of Utah. More than a century later, many of "Ab's" records remain unbroken and the legacy lives on in his custom car. Looking like something Batman would have owned, the story comes full circle when Ab's son Marv, restores the 12-cyclinder, 4800-pound "Mormon Meteor" to its glory days for a ceremonial lap on the salt.
