One night, while riding alone through the meadows, Fenimore Fillmore arrives at a farm that is under attack by gunmen and becomes a hero for helping the farmer, a man named Bannister, fend them off. As a token of his appreciation, Bannister then invites Fenimore for dinner and to spend the night. Early the next morning, Fenimore awakens to discover that his gun is missing; he assumes that Bannister's son Billy has borrowed it to take it to school. In his quest to retrieve his weapon, Fenimore becomes involved in helping Bannister and the other farmers in their ongoing fight against Starek, a powerful rancher whose niece, Rhiannon, becomes the love of his life.
