Doris Attinger (Judy Holliday) follows her husband (Tom Ewell) with a gun one day and sees that he is having an affair with another woman (Jean Hagen). In her rage, she fires at the couple multiple times. One of the bullets hits her husband in the arm.
The following morning, married lawyers, Adam and Amanda Bonner (Spencer Tracy and Katharine Hepburn) read about the incident in the newspaper. The two argue over the case; Amanda sympathizes with the girl, particularly noting the double standard that exists for men and women regarding adultery, while Adam thinks she is guilty of attempted murder. When Adam arrives at work, he finds that he has been assigned the case (on the side of the prosecution). When Amanda hears this, she seeks out Doris and, to Adam's dismay, becomes her defense lawyer.
Amanda bases her case on the belief that women and men are equal, and that Doris had been forced into the situation through her husband's poor treatment. Adam feels she is showing a disregard for the law as there should never be an excuse for such behavior. Tension increasingly builds at home as the couple battle each other in court. The situation comes to a head when Amanda humiliates Adam during the trial, having her female witness pick him up, and Adam later storms out of their house. When the verdict for the trial comes in, Amanda's plea to the jury to "judge this case as you would if the sexes were reversed" proves successful, and Doris is found not guilty.
That night, Adam sees Amanda and their neighbor Kip (David Wayne), who has shown a clear interest in Amanda, together through the window. He breaks into the apartment, pointing a gun at the pair. Amanda is horrified, and says to Adam "You've no right to do this, nobody does!", which satisfies Adam as he feels he has proven his point about the injustice of Amanda's line of defense. He then puts the gun in his mouth, to which Amanda and Kip scream, but Adam merely bites down on it—the gun was made of liquorice. Amanda is furious with this prank, and a three-way fight ensues.
The couple is reluctantly reunited for a meeting with their accountant, where they talk about their relationship in the past tense. They soon become sad when talking about the farm they own, and realize how they love each other. They go to the farm, where Adam announces that he has been selected as the Republican nominee for County Court Judge. Amanda jokes about running for the role as the Democratic candidate.
I love this comedy. Katharine Hepburn and Spencer Tracey are brilliant together! :) xx
