 An innocent country girl (Doris Kenyon) who happens to have a lovely singing voice falls under the influence of a ruthless Broadway producer (Lowell Sherman). At first she s dazzled by the producer s surface charm as well as those bright lights the title refers to, but eventually gets a dose of reality (after accidentally becoming involved in a murder and a race against time to save a condemned man). The film also includes a truly hair-raising train crash.
