In 1907, Lottie Gibson is a vaudeville performer, who also owns a theatrical boarding house in Coney Island; that is, "by the sea". Her clientele are show people. On one of her vaudeville tours she falls in love with a Shakespearean actor, Dennis Emery. When he is to appear in Brighton, Lottie gets him to stay at her boarding house, where his divorced wife—and stage mother—Flora Busch and daughter "Baby Betsy" (although Baby is 17) are also residents. Baby Betsy is infatuated with Mickey Powers, a singing waiter. Mickey thinks that Baby is really as young as her mother forces her to dress, and so, although he has feelings for her, thinks that she is too young.

To add to her troubles, Lottie discovers that her father, Carl Gibson, has taken her money to invest in a Midway attraction. Since she wants to lend the money to Dennis, Lottie decides to try to win the prize for making a parachute jump. Although she wins the prize, the money is not enough. But happily, another prize has been awarded to a man who had been shot out of a cannon, who is revealed as her father, and Lottie has all the money for Dennis. Lottie performs her specialty act, "Lottie Gibson Specialty" as an obnoxious child who refuses to share her parents with a baby brother. She ruefully complains about the awful assortment of men who had been in her life ("I’d Rather Wake Up by Myself").

Jealous Baby Betsy tries to break up the romance between her father and Lottie. Lottie declares that she will give up Dennis, not wanting to come between father and daughter. But, she gives Baby Betsy one of her dresses, and Baby turns into a more appropriate teen-ager. Lottie succeeds in winning over the affections of the young lady, and they go off to the midway where they find Mickey and Dennis, with a happy romantic ending.

The critics praised Booth's performance. "Everyone has long since lost his heart to Miss Booth," wrote Brooks Atkinson in The New York Times.^[3] Walter Kerr praised her "ease and self-assurance". "She is so radiantly confident that the marquee outside glows brighter for having her in the neighborhood."^[4]

In reviewing the 1999 concert, Martin Denton (NYTheatre.com) commented: "...although it finds none of its illustrious authors at his or her best, it is nevertheless a sturdy and pleasant entertainment."^[2]

A cast recording of the original production was released by Capitol Records in 1954.^[5]
