They'd give up everything to dance on stage but could they lose each other? London's East End 1934. Eighteen-year-old twins Marie & Vesta Haskins work at the local shoe factory to bring in a few pennies for the family but they've never given up on their dream of treading the boards in the West End. When a brand new East End club opens its doors the girls audition for the show & are over the moon to land two nights a week with their cabaret act. But little do they realise that the villainous Scoresby brothers are using the club as a front for a very different line of business. Seeing what is going on behind the smoke & lights of the stage sensible Marie vows to leave her job at the club before it is too late but headstrong Vesta has fallen for the Scoresby's handsome right-hand man Teddy & unwittingly leads her whole family into the Scoresby's clutches. Will Marie be able to save her family from disaster? Or will Vesta's determination to become a star tear the Haskins family apart?
