The Bronze Buckaroo

Cowboy Bob Blake and four friends ride to Arizona to help Betty Jackson, the sister of Bob's friend, Joe, who has gone missing. Bob meets the Jacksons' neighbor, Buck Thorn, who says that he'd offered to buy the Jackson ranch but was rejected. Unknown to Bob and his friends, Thorn holds Joe hostage to torture him into signing over his property, which hides a valuable mine. When Betty then disappears, Bob decides to take on Thorn.
