Freddy Hayden (Peter Lind Hayes) is rehearsing for the stage. His college friends are laughing at him. He tells them about his mother, Grace Hayden (real life mother Grace Hayes). She's a stage actress pretending to be a maid for the experience.
This one hits you right in the face with the black-face. I wonder where those stage curtains are now. This is definitely another era. To top off the modern inappropriateness, they do a song and dance praising smoking. The mother-son pairing is interesting although I don't know these actors. I expect more plot with the maid story. Instead, this spends most of it time dancing and singing. There is one interesting dance. I just can't get over the black-face.
