Rustlers’ Valley is a 1937 American Western film directed by Nate Watt and written by Harry O. Hoyt. Lucky is falsely accused of robbing the local bank and assumed drowned in the river while being pursued by a posse. A grieving Hoppy takes exception to remarks made about his presumably dead young friend by local lawyer Cal Howard, and Hoppy knocks him down in public. Howard is engaged to Agnes, the pretty and personable daughter of local cattle rancher Glen Randall, who has borrowed heavily from the town bank in order to buy a herd of breed cattle. Howard’s callously materialistic attitude toward his fiance, coupled with his virulent jealousy of Agnes’ friendship with Hoppy, causes her to break off the engagement. The vindictive Howard pressures the bank to call in its loan on the Randall ranch and conspires to rustle the valuable herd, so that the Randall spread will fall into his hands. This is part of a larger covert plan by the avaricious lawyer to take over the entire valley on the behalf of a shadowy combine.
