Lloyd Nolan is thoroughly convincing as a big-league baseball pitcher in Mr. Dynamite--and never mind that the film never shows the inside of a ballpark! On the eve of the World Series, Tommy Thornton (Nolan), known to one and all as Mr. Dynamite, decides to spend some time at a New York amusement center. Here he meets and falls for Vicki Martin (Irene Hervey), the girl in charge of the ball-tossing concession. When a murder occurs, Vicki is fingered as the most likely suspect. Tommy helps her elude the law, then in the course of a single night tries to subdue the gang of Nazi saboteurs responsible for the killing. Without giving anything away, it's worth noting that J. Carroll Naish (who played every nationality except Antarctican during his long screen career) plays the highly suspicious proprietor of a mind-reading booth.
