When his sister is kidnapped , a young boy (Petersen) set out in pursuit Indians , leaving his parents (Clint Ritchie, Fannon) . He join forces with an alcoholic gold prospector (Richard Boone) who saves him of drowning and helps him to rescue the young girl . They are driven by an elderly Indian (Henry Wilconson) toward a location where lives a strange tribe . He must risk his own life by passing the proof of crooked sky and to avoid his sister to be killed from an arrow archer .
The film is a crossover from the ¨Searchers¨ (John Ford) , also with a pair looking for abducted daughter , and ¨MacKenna's gold¨ (J.L.Thompson) with fantastic inspiration in the rare Indians and the spectacular outdoors . Richard Boone as a drunk trapper is magnificent , he's usual in Western genre and John Wayne films (The Alamo, Big Jake, Shootist). The veteran Henry Wilconson (Last of Mohicans , Crusades, Cleopatra) is also excellent . The film gets sensational landscapes shot in Colorado River and Arches National Park , Moab, Utah . The motion picture was well directed by Earl Bellamy . He was a good professional who served in the US Navy's photographic unit in the WWII and directed more than 1600 episodes of television and catastrophe films such as : Fire! and Flood! and a sequel titled Walking tall II . Rating : acceptable and entertaining .
