While investigating a suspected liaison between her headstrong teenaged daughter and a cabaret musician, young widow Lilia becomes drawn to an exotic nightclub netherworld of Rubénesque belly dancers and nocturnal pleasure-seekers. She strikes up a friendship with one of the dancers, then eventually takes the stage herself, quickly becoming the favorite of both cabaret patrons and the club's hot-blooded drummer. As she gradually sheds her shapeless, matronly housedresses for the flamboyantly sequined bargirl garb, she also begins to emerge from her cocoon of melancholy and loneliness.
