The Great Mike is a horse owned by sensitive farm boy Jimmy (Buzzy Henry). Though the nag is prestently hitched to a milkwagon, Jimmy is convinced that he's got a racing champ on his hands. Convincing big-time sportsman Whitley (Pierre Watkin) that The Great Mike has what it takes, Jimmy and veteran trainer Spencer (Stu Erwin) begin prepping the horse for an important race. A gang of crooks intrudes upon this set-up, threatening the horse's future well-being, but The Great Mike is rescued through the timely intervention of Jimmy's faithful dog. At the time of its release, The Great Mike garnered some good notices, many of them reserved for "Our Gang" alumnus Carl "Alfalfa" Switzer, who essays a comedy-relief part.
