Ulamax Faith (Alanson) is a struggling musician whose efforts did not pay. One night disappointed, he talks to his "Plastic Sweetheart" a realistic-looking mannequin in a shop window (Ozdemiroglu) that, "he could even sell his soul to the Devil for fame"...and then he sees the Devil himself (Poyrazoglu). They make a deal that Faith, will sell his soul to the Devil and the Devil will strike him to fame, using the record executives, venue owners and commercial executives whom he had their souls. However the times had changed, and the human had proved to be more evil and smarter than the Devil himself.Overall it's a fine comedy with a touch of drama. Some special effects might be seen as poorly done, however the Turkish cinema in 1980's was still not at a good financial and technical level...still those were an improvement. Aspects of the changing Turkish society, moral values and music industry...and the struggles of the ones (even the Devil) whom cannot keep up with this progress are visible. One of the well-done movies of the decade.This is also a musical movie which has good adult oriented pop tunes done by Mazhar Alanson's band M.F.Ö. for this movie. The band's bassist-vocalist Özkan Ugur also acts as a band member. Other original member of the band, guitarist-vocalist Fuat Güner could not participate that time due to health problems (altough might have been credited, not sure about that)
