When dentist Dr. Bruce Fleckstein is murdered in his Long Island, New York, office, the townswomen gossip about who may have killed the flirtatious man. Former journalist Judith Singer is questioned by Detective David Suarez, even though she had seen the dentist only once. Later, Judith’s lawyer husband, Bob, reports rumors that Dr. Fleckstein was about to be indicted on pornography charges. When Judith’s friend, Mary Alice Mahoney, admits to having an affair with the dentist and allowing him to take intimate photographs of her, she asks Judith to investigate. Learning that several women in town also had affairs with Dr. Fleckstein, Judith asks her previous employer, News Day, to re-hire her for a freelance story. She begins by interviewing Dr. Fleckstein’s brother-in-law, Dicky Dunck, and his wife, Brenda, about how the family is grieving. When Judith later visits the dentist office, she encounters Detective Suarez, who reports that her presence at the crime scene has made her a suspect. Sometime later, Judith recruits help from her friend, Nancy Miller, whose lover, “Cupcake,” is a police officer. Nancy learns from Cupcake that three women have been identified from intimate photographs at Dr. Fleckstein’s home, but their friend, Mary Alice, was not among them. One day, Judith’s home is vandalized with a warning for her to drop the investigation, and her husband, Bob, learns she has returned to work as a journalist. Unsupportive of his wife, Bob calls Detective Suarez to their home in hopes of putting a stop to Judith’s story. The police officer learns that Judith possesses crucial information about the case, but she refuses to share her sources. Detective Suarez leaves angry, telling Judith that she is still a suspect, but later returns to her home and shares information about the case. In time, Dr. Fleckstein’s wife, Phyllis, agrees to an interview with Judith. Phyllis claims her husband was innocent to the pornography charges, and that her brother, Dicky, who owns a printing company, was the one printing pornography, unbeknown to Dr. Fleckstein. Dicky had named his brother-in-law as the responsible party to protect himself from criminal charges. Phyllis believes someone was also trying to destroy her husband’s reputation by linking him to organized crime. Detective Suarez later returns to Judith’s home, and the two decide to become partners. When the detective tries to kiss Judith, she rebuffs his advances, although he argues that he is not seeking a meaningless affair. Judith admits her attraction to Detective Suarez to her friend, Nancy. Sometime later, Detective Suarez shows Judith the photographs that Dr. Fleckstein took of his many lovers, and Judith identifies Dicky’s wife, Brenda, in one of the pictures. Meanwhile, Bob is angry that Judith has not given up on writing the story. Giving it some thought, Judith surmises that Dr. Fleckstein took Brenda as a lover to blackmail Dicky into not testifying against him. Based on her theory, Judith and Detective Suarez conclude that Dicky murdered his brother-in-law, and Judith meets with Brenda to evoke a confession. However, Brenda believes Dicky is innocent, and admits to thinking that Dr. Fleckstein was in love with her. When Dicky asks Judith for a meeting, Detective Suarez decides to send her undercover, wearing a wire. Later, Bob threatens to leave Judith if she insists on going through with the story, and she drives away in tears. Down the road, Phyllis unexpectedly appears in the back seat of her car, holds Judith at gunpoint, and forces her to drive to her home, where Dicky awaits. Judith realizes the siblings are working together, and Phyllis presses Judith for information. When Phyllis leaves, Dicky holds Judith at gunpoint, but she begs for release. Dicky admits that he showed Phyllis the intimate photograph of his wife, Brenda, and she became enraged about her husband’s infidelity. Phyllis then forced Dicky to her husband’s office, where he waited in the lobby, unaware that Phyllis was murdering Dr. Fleckstein. Judith remains hostage as Phyllis tries to take the gun back from Dicky. However, he refuses and accidentally shoots his sister as she charges towards him. As Judith calmly takes the gun from Dicky and orders him to help the wounded Phyllis, Detective Suarez and several officers arrive at the scene, and Judith is praised for her bravery. Returning home, Judith encounters her angry husband, but he realizes she has endured trauma, and softens his approach. Sometime later, Judith proudly turns in her story to News Day, and it makes the front page. She discusses her next report with her friend, Nancy, who inquires about Judith’s flirtation with Detective Suarez. Judith reveals her loyalty to Bob, who, she explains, is trying to be a better husband. Before Nancy leaves, the friends share a few jokes about dentists.
