"Singin" in the Rain" tells that in 1927, Linna and Don were a very famous on-screen couple. With the rise of movies, Linna fell into a great predicament. Although she had a plump figure and a pretty face, she didn't have a good voice. When recording sound movies, she also made a lot of fools, in order to match Lina with a good voice. Don introduced Kathy to the production team and asked Kathy to dub it. With the addition of Casey, Linna's popularity is also rising. But at that time, Linna was dazzled and refused to recognize Cathy's contribution, so her actions aroused dissatisfaction among everyone.
