On the Great White Trail was the second B-picture inspired by Laurie York Erskine's "Renfrew of the Royal Mounted" books. James Newill is back as Renfrew, who on this occasion tries to solve a robbery and murder. The villains are a gang of fur thieves who've been targeting the trading posts owned by Andrew Larkin (Robert Fraser). Renfrew's mission is compromised somewhat by the presence of Larkin's headstrong daughter Kay (Terry Walker), who insists upon participating in the manhunt. Originally produced by Criterion Pictures, On the Great White Trail was distributed by Grand National.
