So’s Your Aunt Emma!

Emma Bates, an old spinster, decides to travel to New York City to see the boxing match featuring Mickey O'Banion. She leaves her sisters behind, who are appalled by the decision. The visit sets the stage for a web of crime and romance that drives the rest of the story.

Emma arrives in the city without tickets and finds the fight sold out. Reporter Terry Connors offers his spare ticket, allowing her to witness the event. This chance encounter links Emma to the evolving crime plot and Terry's gaze into the underworld.

Terry, who usually covers crime, is reassigned to sports but continues chasing the Rex Crenshaw kidnapping. He skips a planned visit to the marriage license office, triggering a furious breakup with his fiancée Maris. The personal and professional stakes begin to intertwine.

At the fight, Terry suspects Mickey's manager Gus Hammond of involvement with the Crenshaw kidnapping because Crenshaw represented Hammond's rival. The suspicion deepens the clash between boxing and criminal power. The stage is set for a confrontation between Terry's journalist instincts and the gang's schemes.

Two of Hammond's henchmen, Joe and Duke, spot Terry talking with Emma and mistake her for Ma Parker, the feared mob figure. They warn or threaten Emma, thinking she is meddling in their mob business. The mistaken identity raises the danger Emma faces.

Flower Henderson, Hammond's rival, spots Hammond at the fight and orders his own goons to deal with Joe and Duke. Henderson also instructs Zelda to charm Mickey into a favorable position. The criminal web tightens around Emma and the fight crew.

The fight ends with Mickey's fixed victory, delivering the outcome the gangs expect. The crowd believes the result is legitimate while behind the scenes the organizers are manipulating the match. Hidden control of the fight world becomes evident.

Emma goes to Mickey's dressing room after the bout and tries to persuade him to train at her country home. She uses her Ma Parker persona to present herself as a tough mentor. The suggestion ties Mickey’s future to Emma's plan and to her influence over her sisters.

Henderson's men kill Joe and Duke, and Emma is quickly branded a suspect since she was the last person seen talking to them. The accusation threatens to derail her alliance with Terry and complicates the investigation. Emma negotiates to clear her name as the case widens.

Emma and Terry visit Henderson's nightclub, where Maris has begun performing. Zelda keeps pressuring Mickey and trying to tip Hammond off with a phone call. The club setting intensifies the entangled loyalties and deceptions.

One of Henderson's men tries to secure a deal for the next fight with Mickey. Terry steals an envelope meant to be delivered from Henderson and gives it to Emma to guard, sensing a larger scoop. The pieces of the criminal scheme start to come into focus.

Hammond shoots Mickey at the hospital, sending him into treatment. Emma and Terry decide that Emma should infiltrate Henderson's gang by posing as Ma Parker to locate Rex Crenshaw. The plan heightens the danger as Emma risks her life in the Crenshaw case.

Emma poses as Ma Parker to infiltrate Henderson's gang, but Hammond rushes in and shoots Henderson. Emma is kidnapped along with Maris as a hostage, raising the stakes for Terry's rescue mission. The double-cross leaves everyone racing against time.

Terry, joined by detective Miller, tracks Hammond to the hideout and storms the location. They rescue all missing persons, including Rex Crenshaw, and bring the criminals to justice. The scoop finally yields a legitimate breakthrough.

Terry receives a promotion, a raise, and a two-week honeymoon in recognition of his achievement. Mickey accompanies Emma to the country and begins training under her tough Ma Parker persona, while she introduces him to her two sisters. A new life in the country marks the end of the adventure.
