Judy O'Brien is an aspiring ballerina in a dance troupe. Also in the company is Bubbles, a brash mantrap who leaves the struggling troupe for a career in burlesque. When the company disbands, Bubbles gives Judy a thankless job as her stooge. The two eventually clash when both fall for the same man.
A really fun film that I found in my Maureen O'Hara TCM 4-pack that I highly recommend if you enjoy films from that era. I like the two films I've seen so far from Arzner, who was one of the earliest and most successful of female directors and I believe the first openly lesbian one--the other work I've seen of hers is the great pre-Code look at alcoholism, 'Merrily We Go to Hell'.
This is great if you either like musicals from the era, are a Maureen O'Hara or Lucille Ball enthusiast (holy, she was unbelievably a knockout in her early filmic days!) or are simply curious about the works of early female and/or lesbian directors. Arzner--at least in the two films I have seen from her thus far--showed she truly deserved to be successful in the industry.
