The New York-based private investigation firm Odyssey Detective Agency employs three agents: the middle-aged, womanizing John Russo, the younger,
hippie-ish Arthur Brodsky, and the nervy and anxious Charles Rutledge. Their cantankerous boss, Leon Leondopolous, tries to keep his bumbling agents in line while carrying on a poorly-disguised affair with his secretary Amy. Odyssey is investigating two separate married women: Angela Niotes, the aged but glamorous wife of a British tycoon, and Dolores Martin, a beautiful blonde. While attempting to follow Angela from the
Manhattan heliport, John meets a taxi driver named Deborah Wilson. The two are instantly infatuated, and John makes plans to see Deborah (whom he calls "Sam") later that night. At the same time, Charles falls for Dolores as he spies on her in the lobby of a hotel. Arthur (who juggles a series of passionate romances throughout the film) is worried for each of his co-workers, but assists each of them in growing closer to their objects of affection: he helps John get away from his on-again off-again partner, country singer Christy Miller, and devises a plan for Charles to have a conversation with Dolores at a roller rink. He learns that Dolores is indeed cheating on her husband with Jose, a playboy with whom she plans to elope. The next morning, John recounts his tryst with Deborah to Leon; he worries that he has become too old for younger women. Meanwhile, Christy, who has figured out what John has done, decides to get back at him by starting a relationship with Charles. The two head to
Midtown, where they run into Dolores at an upscale clothing store. Christy later tries to initiate a sexual encounter with Charles, but he is already too infatuated with Dolores to reciprocate. Meanwhile, John and Arthur track Angela and her young son to a toy store. John confesses who he is, but Angela is not surprised, as she knows that her husband is himself cheating on her. An attraction grows between John and Angela; once again Arthur helps his friend by pretending to be John's son. Deborah runs into Angela and John at the latter's apartment; she does not appear to be bothered by John's simultaneous desire for the two women. Meanwhile, Dolores almost kisses Charles at one of Christy's concerts, while Christy herself confesses her attraction to Jose. When Charles follows Dolores back home, she eventually leaves her apartment and kisses him before running away. Charles spends the night on a bench outside of Dolores' apartment, following her to a courthouse where Christy observes her and Jose enter a judge's chambers. Christy invites most of the other characters to another concert as Deborah and Angela have a secretive conversation. Later, Angela tells John that she is returning to Europe with her husband and son; she has arranged Deborah to take her place and nurse his broken heart. At the concert, Charles is reunited with Dolores, who reveals that she went to the courthouse to obtain a divorce. He proposes marriage to her (which she accepts). Christy introduces Jose, her fiancé, to the concert's audience. The following day, Charles and Dolores as well as Christy and Jose are married in a double wedding. John tearfully sees Angela off, then returns to his cab, where Deborah is waiting. ==Cast==
