How to Murder a Millionaire

Irma's car brakes fail as she drives home, sending her vehicle crashing through the garage door. The accident exposes the fragility beneath Irma's luxurious life and hints at a pattern of danger surrounding her. This incident sets the tone for the increasingly perilous events to come.

Irma confides in Loretta, her trusted friend, about her unhappy marriage and growing fear. They discuss trust, protection, and the possibility that Irma is a target. The talk foreshadows the threats looming over Irma.

Loretta and Gilbert visit Irma and Walter to celebrate the couple's anniversary. The evening devolves into arguments as Irma and Walter air their marital grievances. The confrontation hints at underlying resentments and danger.

That night, Irma hears a prowler and calls the police for help. Investigating the noise, she becomes locked in the garage with smoke pouring from a car. The police arrive and dismiss it as a false alarm, noting Walter in the garden.

Walter presents a back massager in Irma's bathtub, a risky gadget in a tense moment. She plays with a brush, triggering sparks that suggest she could have been electrocuted. The scene amplifies Irma's fear of deliberate harm at home.

At a restaurant the next day, Irma wonders aloud whether the accidents could be attempts on her life. Walter arrives with another woman, giving Irma further cause for suspicion as he gifts a necklace. The encounter deepens her paranoia about her marriage and safety.

Irma learns from a mechanic that someone cleaned out the brake fluids in her car before the crash. This confirmation solidifies her fear that someone is actively trying to harm her. She resolves to uncover who is behind the acts.

Irma discovers a gun hidden in a box that Walter had placed in a drawer. She calls the police, accusing her husband of trying to kill her, and then leaves home with a few clothes and valuables. The threat to her life pushes her toward taking matters into her own hands.

Danny and Teresa, who advocate robbing the wealthy, target Gilbert and Loretta's home. Irma reveals to Teresa that she is worth about $3 million. The scene sets the stage for a clash of greed and self-preservation.

Inside Irma's home, Teresa helps Irma steal some jewelry while Loretta arrives to seduce Walter. Irma then acts quickly to subdue Danny, knocking him out with a statue. The attempted theft goes wrong, heightening the danger.

Walter goes to Gilbert's office and then follows a trail of purchases to locate Irma. He learns Irma bought a sofa and follows the delivery to a mysterious address where Danny is seen moving furniture. He offers Danny $5,000 to locate Irma and bring her to justice.

Irma hires a maid service so she can enter her home without raising suspicion and pursue her own jewelry. Inside the home, Teresa helps Irma steal more pieces while Loretta arrives and tries to seduce Walter again. The double-dealing escalates the household's peril.

Gilbert enters Walter's residence, retrieves a gun, and then phones Danny pretending to be Walter to convince him to kill Irma for $50,000. He also learns about a flight to Acapulco that Danny has booked. The deception deepens the threat against Irma.

Danny goes to the airport to meet Irma after the plan to kill her is hatched. Irma warns Danny that Walter has offered money to kill her and counters with a higher price, proposing $100,000 to spare her life. The standoff raises the stakes for both sides.

Irma learns of a wedding at the Ambassador Hotel and hides under the wedding cake to observe. Walter is present, and Gilbert reveals that someone is trying to kill Irma. A struggle ensues, Gilbert is subdued and arrested, and, in the end, the lovers and friends celebrate a peaceful conclusion.
