Child actor Peter Robbins, who provided the voice of the title character in the classic cartoon special A Charlie Brown Christmas, appears in the flesh as 10-year-old Joey Walker. When Joey runs away from his widowed mother (Pippa Scott) in hopes of joining the Cavalry, Sgt. O'Rourke (Forrest Tucker) takes it upon himself to persuade the boy to return home. There's only one problem: During his brief stay at Fort Courage, Joey has proven to be the best trooper in the whole place! ~ Hal Erickson, Rovi
