It's time for another titanic triple feature of mystery, adventure and wild Northwest action alongside Kirby Grant (TV's Sky King) and that most wondrous of pups, Chinook! Based on the series of sensational stories of James Oliver Curwood, the films detail the adventures of a Mountie and his canine partner fighting crime within the confines of the Arctic Circle. Trail of the Yukon begins the series with Grant playing Bob MacDonald of the RCMP (the name would eventually become the more well-known Rod Webb later in the series) coming to the aid of double-crossed bank robbers. Fangs of the Arctic sends Corp. Rod Webb undercover as a trapper to uncover a killer in the fur trade. Finally, Northern Patrol finds Rod and Chinook unraveling a locked-cabin murder mystery.
