Sex and the Single Girl

A colleague at Stop magazine writes an article about Dr. Helen Gurley Brown, shaking her reputation. Helen is offended, believing the piece discounts her experience in sex and relationships. Bob Weston decides to pursue a follow-up interview, but Helen refuses.

To get closer to Helen and gather material for Frank, Bob Weston masquerades as Frank Broderick's patient. He attends Helen's office under the false identity, aiming to win her trust. His plan is to report back to Frank with her advice.

During their first sessions, Bob acts shy and smitten, softly courting Helen. She keeps boundaries, insisting the therapy is about Sylvia's relationship with Frank, not about Bob's own interests. The dynamic hints at something more complicated than professional help.

After a staged suicide attempt, the mood shifts and Bob and Helen end up kissing in her apartment. Bob realizes he is genuinely developing feelings for Helen, complicating his original mission. Helen begins to worry about falling for a married man.

Helen panics about her attraction and follows her mother's suggestion to meet Sylvia. She encourages Sylvia to return to work at Frank's office, where the two women first met, hoping to stand together against rival scheming.

Sylvia, encouraged by Helen's counsel, eventually agrees to work with Frank again, repairing their strained marriage. The decision sets the stage for the bigamy misunderstanding to unfold later. Frank remains unaware of Bob's true identity.

Bob pushes the plan further, arranging for Gretchen and Susan to pose as Mrs. Broderick and a second 'wife.' Gretchen even cancels an audition to show up at Helen's office, creating a scene where three women claim to be Mrs. Broderick. Helen grows increasingly confused about who is really Frank's wife.

The chaos culminates as three women claim to be Mrs. Broderick, and Sylvia calls the police. Frank is arrested for bigamy, complicating everyone's lives and triggering the unraveling of Bob's ruse.

Helen visits Sylvia with Dr. Rudy DeMeyer and learns about the article's implications for her patients. In the process, she discovers that the man visiting her office is not Frank, but Stop's managing editor Bob Weston. Shocked, she asks Rudy to take her away to Fiji.

Bob refuses to allow Stop to publish anything about Helen, leading to his termination. The fallout marks the end of Bob's deception and the start of a string of personal reckonings.

In a frantic finale, the couples chase each other through city streets in cars and taxis toward the airport. Tensions peak as misunderstandings collide with romantic resolutions, setting the stage for the film's outcomes.

At the airport, Frank and Sylvia reconcile and prepare to depart for Fiji, while Rudy and Gretchen plan a trip to Hawaii. Bob forgives Helen, who soon travels with him to Las Vegas to marry, after Bob secures a new job with Dirt magazine. The film closes with the couples finding their new arrangements.
