This is a bit of comic fluff that is mostly notable as a a very early starring vehicle for Joan Fontaine. She is cute, but quite mannered, especially when the script calls for her to laugh. The plot concerns a milk magnate's son who is studying to be an ichthyologist and who agrees to drive a milk truck for daddy's company for one month on a bet. He meets up with socialite Joan whom he mistakes for a domestic and much silliness ensues. Future cowboy star Allan Lane is charming as the fish student cum milkman and Hedda Hopper is good for a few laughs as Joan's ditsy mother. Of course Joan and Allan hate each other on sight, but things progress as one would expect in a 'B' romantic comedy of this period.
Look for Jack Carson in an uncredited bit part as a roller coaster attendant, and Lee Patrick as a lady who is ready to kiss any milkman who appears at her kitchen door. (The small part of Allan's cousin is played by an actress named Vicki Lester, which of course is the stage name of the heroine of "A Star Is Born," which came out the previous year. Since her credits only begin in 1937, I'm guessing she took her name from the movie.)
