Cast & Crew
Canadian mountie Gale Farrell and his partner Pat come upon a wounded man from Twin Oaks who tells them that two feuding fur trappers, Jim Foster and Bob Reynolds, killed five men for revenge after Foster's cabins were raided and burned. While en route to Twin Oaks, The Raven, a wanted killer, tries to steal Gale's horse, but he apprehends him and finds a note signed with the initials "C.R.," which has recommended The Raven to Henry McClain, proprietor of the Trappers' Roost saloon in Twin Oaks. Meanwhile, in Twin Oaks, McClain schemes to exacerbate the Foster-Reynolds feud so he can procure their furs, which have a combined worth of $100,000, and cause each to accuse the other of theft. Gale arrives with a tattoo on his arm that matches The Raven's and reports to McClain for duty, claiming he jumped mountie Gale Farrell and stole his uniform and identification. While Doc Martin removes a bullet from Bob Reynolds, Bob's sister Ruth appeals to Gale to stop the fighting. Believing Bob raided and burned his camp, Jim interrupts a fur sale between Bob and McClain and finds one of his marked furs. On McClain's orders, Gale steals Bob's furs and finds a Foster fur among them. Bob then goes to Jim armed for a fight, but Gale tells Ruth it was McClain who robbed Bob, and the two of them stop the gunfight. Gale then convinces Bob and Jim that McClain has duped them into accusing each other, and asks them to pretend to continue the feud until they know who is behind McClain. After Gale then returns each man's furs, which were hidden in McClain's cabin, Martin shoots both Bob and Jim in the back. Wounded, Jim rides to Ruth, and she sends him to Martin before rescuing Bob. Gale, meanwhile, visits Martin, who tells him Jim woke and accused Bob of trying to kill him. A man named Rogers whose first initial is "C" then arrives and accuses Gale of being an impostor, and Gale escapes into the woods, eludes McClain's men, and rides to Bob, who says the shot that wounded Jim came from the window. When Gale finds a string of birds outside the window, he knows the killer is Martin, whose hobby is hunting. To secure proof that Martin is McClain's boss, Gale agrees to go undercover to help Martin find the killer. Martin tells McClain Gale's whereabouts and McClain goes after him. A shootout ensues and Gale, with Pat, apprehends McClain and Rogers, then arrests Martin. Gale is then united with Ruth.
According to the Hollywood Reporter, producer Maurice Conn was planning to entitle this film G-Men of the North, but Warner Bros. held the property rights to the use of the word for its 1935 film G-Men, and Albert Howson of Warner Bros. sent a letter to Conn warning him not to violate Warner's exclusive rights to the word. The title card for this film reads: "James Oliver Curwood's Wildcat Trooper." The Hollywood Reporter production chart from the first day of shooting lists Joan Barclay, Paul Fix and Harry Worth in the cast along with Kermit Maynard, although it has not been confirmed that they were in the final film. Also listed are Stephen Norris for screenplay and Charles Hutchison as director, although they did not receive screen credit for the film.
