When the local territory strikes an oil boom and Molly Vernon and her mother are about to become rich, Bud Harris, in love with Molly, leaves for other parts. When the oil bubble on the Vernon property burst, he returns to find the place encumbered with debt. To pay it off he enters a horse race. Bush, who holds the mortgage, is trying to foreclose, having secret information about the land. He conspires to keep Bud out of the race and lays heavy bets, knowing that Bud is the only formidable rival. Four men jump on Bud as he leaves the Vernon home at night. They take him to a secluded cabin and lock him in. However, Bud's horse finds the place and breaks down the door. When the race is about to start, Bud rides up and flabbergasts the opposition. After a thrilling ride, he wins the race, at the end of which he pulls Bush from his horse and administers a sound thrashing. Subsequently, oil seepage is found on the Vernon ranch and the boom is on again, with Bud and Molly happy together.
