When Daniel Collins, an erstwhile producer of college musicals, hears singer Frances Lewis perform at the Zodiac Club, he offers her several suggestions on how to improve her delivery. Mike Armstrong, a fledgling talent agent who has a crush on Frances, is so impressed by Danny's ideas that he proposes they become partners in a talent agency. As the years pass, the agency grows successful. Danny, the creative member of the team, is busily developing a new television program to showcase singer Joan Merrill when Mike learns that Frances has just divorced her wealthy husband. Soon after, Frances, a shameless opportunist, visits Mike at his office to ask for a spot in the show. After Mike offers her a supporting role, Frances, exploiting Mike's feelings for her, insists on being the star. When Mike asks him to redesign the show for Frances, Danny, skeptical of Frances' talent, refuses, causing the partners to argue. Valuing Mike's friendship, Danny relents and agrees to go to Frances' apartment to tell her the good news. There, Danny and his friend, One Note Davis, watch as Frances' maid, Kitty Brown, dances and sings while cleaning house. Impressed by Kitty's performance, Danny hires her for one of the production numbers. Soon after, a tipsy Frances returns home from her date with a tobacco magnate. Angry at Frances' betrayal, Danny warns her not to lead Mike on and offers her Joan's part. When Frances is late for the audition the next day, Mike goes to her apartment and discovers that she is being detained by The Three Stooges, whom Danny has hired to pose as gangsters to prevent her from leaving the building. After Mike phones the studio and learns that Kitty has been assigned to replace Frances, he cancels the show and dissolves the partnership in earnest. While at a diner one night, One Note and Danny meet Mike, who tells them he plans to marry Frances and has bought the Skyline Club to showcase her. Although both Mike and Danny boast of their success, in reality, they are miserable without each other. Soon after, Danny receives a telegram from movie mogul James Anderson, asking to audition some new talent. When Danny decides to develop a show around Joan and Kitty, Kitty, who wants to reconcile the former partners, suggests staging it at the Skyline Club. Knowing that Mike will refuse their request, One Note suggests asking Frances if they can use the club in return for the material that Danny is developing. When the ever-ambitious Frances agrees to let them use the club in exchange for making her the star, Danny refuses. Kitty, who has fallen in love with Mike, decides to sacrifice her part to Frances and disappears, forcing Danny to offer the role to Frances. Determined to become a star at any cost, Frances tells Mike that the revue has been conceived for the club, neglecting to inform him that it is really a Hollywood audition. On the night of the performance, Mike sees Anderson in the audience and learns about the audition. Thinking that he has been betrayed by both Frances and Danny, Mike confronts his wife, who declares that her career takes priority over their marriage. After Mike orders her out of the club, he is about to accuse Danny of betrayal when One Note stops him and explains that one of the reasons that Danny staged the audition at the club was to expose Frances as a ruthless opportunist. Mike then agrees to let the show go on, and as Kitty dances her dazzling finale, Mike and Danny shake hands.
