Rosie (Joan Blondell) and Marie (Glenda Farrell) are two manicurists from Kansas City. Rosie has been seeing a gangster who goes by the name of Dynamite (Robert Armstrong) and just before he leaves for St. Louis, he gives Rosie an engagement ring. While Dynamite is out of town, Marie, who thinks Rosie could do better, encourages Rosie to go out with one of their rich clients. Rosie reluctantly goes along with it and the whole thing goes horribly wrong when it turns out her date is also a criminal who steals her engagement ring. Things get even worse when Rosie hears that Dynamite is coming back to town earlier than expected so she doesn’t even have time to fix things.
Rosie and Marie know Dynamite will be furious when he finds out what’s happened, so they disguise themselves as members of the Outdoor Girls of America and get on a train headed to New York. But Dynamite finds out what’s going on before they can leave the station so he follows them to New York. Once in New York, Rosie and Marie hop in a cab with two businessmen and stick with them as they board a ship headed to Paris with Dynamite hot on their trail.
While on the ship, Dynamite meets millionaire Junior Ashcraft (Hugh Herbert), who is heading to Paris to put an end to his wife’s affair. When Marie and Rosie hear about a rich man being on board, they can’t resist posing as manicurists so they can try to play him. The plan falls flat when Junior reveals the truth, but Junior is still willing to help the ladies out. Once they get to Paris, Junior comes up with a plan to stop his wife’s affair by having Rose pose as her lover’s boyfriend. Little does he know his wife and the detective he’s hired to follow her have plans of their own.
Joan Blondell and Glenda Farrell are two of my favorite sassy, fast-talking pre-code actresses so any movie that features both of them is going to be very intriguing to me. Kansas City Princess starts out being so much of what I love about many Warner Brothers pre-codes — fast-paced, funny, and full of snappy dialog — but, unfortunately, the movie loses a lot of momentum about halfway through. Considering how many things Kansas City Princess had working in its favor and it did start out looking promising, the fact that it failed to hold my interest for 64 minutes was pretty disappointing. Not even the fabulous chemistry of Blondell and Farrell could save it. They did the best they could with what they had to work with, it’s just they didn’t have much to work with.
