The law is the law. No exceptions. So Sheriff Sam Barrett saddles up a deputized posse and rides in pursuit of an accused outlaw: his son Logan. Meanwhile, Logan is on the run, living by his wits and attempting to clear his name of murder. Justice rides hard in Return of the Frontiersman, a shoot-''em-up filled with horseback chases, raging gun battles and men who know how to take - and deliver - a swift sock to the jaw. Gordon MacRae plays Logan, heading a cast that includes Rory Calhoun and Julie London. MacRae adds a couple tunes for good measure. And when he offers London a buggy ride at picture''s end, it''s hard not to recall the "surrey with a fringe on top" that awaited MacRae in the smash musical Oklahoma!
