I did like this film very much,not only because the Hungarian volcano Marika Rökk in a double role and the highly reputed stage actor Will Quadflieg. There is the story of the two twin sisters,one good,one bad. Kora,the dark character,and Mara both are variety artists and act together on stage as a couple.But Kora knows what ways to go to make career and becomes famous-and she doesn't care about what happens with her sister.As Mara fells in love with the violin player Varany,but Kora grabs him,they have an altercation,and Mara,in a moment of affection, shoots her sister. From now on,although unwilling,she has to play the role of Kora.But Kora was involved in dark affairs with a ring of spies,and it especially gets hard for Mara,when she meets Varany again... The story is not new,but told in a quite exciting and amusing way. The film doesn't have a special meaning or message,and ,of course,as many of the German films of these times,it doesn't give a political statement - it's just pure entertainment. A quite enjoyable musical and the try of a German spy and action drama. The best scenes in the film are the music-scenes, where wonderful Marika can show what she has learned during her time as a circus artist.
