Boxing manager Arthur "The Professor" Duffy (Robert Keith) is saddled with a punch-drunk pug named Soldier Fresno (Karl Lukas). Hoping to transform Fresno into a winner, Duffy begins injecting the boxer with a special stimulant recommended by horseplayer Boots Murphy (Frankie Darro). Before long, the reinvigorated Fresno is headed from the championship -- but things take a disastrous turn when Duffy decides to improve his chances by giving Soldier an extra "jolt." ~ Hal Erickson, Rovi
