Un monde à nous

Debby sings to herself at her boring job for the Bureau of Navigation in Liverpool, but when she rejects her boss's unwanted advances, she is fired. However, a member of a band has been listening to her sing outside the office window and offers her a chance to sing with them. She falls in love with a famous guitarist who also joins the band, but he still harbors feelings for an actress he once loved years ago. Debby confides her feelings to a wife of a band member, but neither girl realizes the tape recorder has been left running. When the boys arrive, everyone hears their conversation.
