Synopsis by Hal Erickson
In Frontier Investigator, Allan "Rocky" Lane plays the title character, spending the bulk of the picture searching for the man who killed his brother. The fact that Lane was central to the plotline was an oddity, since in most of his Republic starrers he usually functioned as last-minute problem solver, with the plot intricacies handled by the supporting cast. Lane's co-stars in Frontier Investigator include two actors who'd go on to even greater fame on television. The heroine is Gail Davis, TV's Annie Oakley, while Davis' boyfriend is portrayed by Clayton Moore, the future Lone Ranger.
