The Rain takes place at the end of the years when the Hollywood world, accustomed to silent films, met with sound film technology. Don Lockwood, who was a famous actor at the time, has a successful voice that ensures that he adapts quickly to sound films. However, her acting partner Lina, who does not have a pleasant voice, turns their new movie into a fiasco. Looking for a solution with his friend Cosmo, Don decides to voice Lina's scenes with Kathy, whom he has just met and fallen in love with. Meanwhile, Lina, who insists on believing the love she and Don played on stage, is real, causes things to become even more complicated than they really are. It turns into a very entertaining, almost improvised musical with the dance performances that are performed partially independent of the story and the comedy created by the characters who are always smiling.
