 A former baseball player (Bendix) spends his days (and eventually loses his various jobs) watching baseball games. His favorite nemesis is the umpire, the "lowest a man can get." After his last baseball- related unemployment, his father-in-law, an ex-umpire, suggests that Bendix use his love of baseball and become an umpire. Against his wishes but to appease his wife, he attends umpire school, where he tries everything to get thrown out, providing some funny scenes. The school director Frawley eventually convinces him to take it seriously and he becomes "Two-Call" Johnson.
