Lloyd Bridges stars as Colton, a former Union cavalry captain who rides the American West in search of himself. His journey finds him crossing paths with a range of men and women emblematic of the best and worst in humanity. Introspective and emotionally complex, The Loner stood apart from the typical "white hat/black hat" Western entertainment of its day, bolstered by Bridges' nuanced performance and Serling's steady hand at the reins.
