Women are the downfall of Wacky Waters, the crack pitcher of the Sox baseball team; whenever Wacky falls for a female, his pitching average also falls. Consequently, when movie star Pepita Zorita visits the game to sell kisses for War Bonds, Dan Hannigan, the Sox's manager, becomes concerned. After savoring $300 worth of kisses from the glamorous Pepita, Wacky proceeds to lose the game to the opposing team. When Updyke, the representative of the bank that owns the team, arranges for Pepita to accompany the Sox on the road as a publicity stunt, Hazel Jones, the wife of player Hippo Jones, determines to keep Wacky and Pepita apart in the interests of the team. Despite the combined efforts of Hazel and the other wives, Pepita and Wacky sneak away one day and are secretly married. Wacky's marriage intitiates a losing streak for the pitcher, and the team sees their penant hopes evaporate. The Sox and their wives are relieved when Pepita accepts a starring role in Hollywood, but when she finishes production early to hurry back to her husband, Hazel decides to take action. When, in the middle of the World Series, Pepita calls Wacky to arrange a meeting in Kansas City, Hazel, accompanied by fellow baseball wives Kitty McLoan and Joan, beat Wacky to the airport and kidnap Pepita. The three women hold Pepita hostage in a Kansas City hotel room, sending Wacky nightly telegrams from his loving wife. Pepita's continual shrieks bring house detective Dugan to investigate, but Hazel placates him with a story about her ventriloquist sister. Hazel's plan works until the second to the last game of the series, when Kitty is listening to the game on the radio and hears that her husband Spike is kissing a blonde. Kitty becomes furious, and in the ensuing chaos, Pepita steals a bellboy's uniform and escapes the hotel to return to Wacky. With one game remaining, Hazel schemes to keep the newlyweds apart. As Pepita awaits Wacky in the bridal suite, Hazel pretends to make amends by spraying her with perfume. The atomizer holds red dye, however, and after Pepita's face is covered with red spots, a phony doctor hired by the team diagnoses that she has a rare rash and must be quarantined. The next day, as Wacky pitches the final game in the series, the Sox are losing until Pepita enters the stadium and cheers her husband to victory.
