Betty Miller (Diana Lynn) and her all-woman band are in a tough spot. They've been out of work for a long time and the bills are mounting. When a dopey guy named Herbie (Eddie Bracken) is discovered by Miller, their problems might be over. The guy sings like Bing Crosby* and the audiences love him. The problem is that they need to pay their hotel bill in order to get to their big break--a radio broadcast. So, she instructs the band members to sell interest in Herbie. The problem is that they sell 125% of the stock in him...and they are able to leave the hotel but they could end up going to jail. Betty's way of dealing with this is to pay Herbie a paltry $50 a week--even though she's getting paid a thousand a week (and soon more) for Herbie. In essence, she's cheating Herbie out of a fortune...and seems more concerned with saving herself from jail as opposed to what's best for Herbie. Sadly, Herbie is smitten by her...and doesn't realize that the hundreds of thousands he thinks she's banking for him is gone. Not surprisingly, the investors are NOT pleased when they learn the truth.
While the film is supposed to be a romantic comedy, the plot is so cruel and selfish that I was really distracted. I hated Miller and was surprised the writers and studio would ask a cute actress like Diana Lynn to play such a dishonest and selfish character. About the only thing I did like about the movie was seeing Lynn play the piano--and she was a genius at that. Otherwise, the film is just not worth your time.
*By the way, the reason Bracken sounds like Bing Crosby is because it IS Bing Crosby's voice in the film. I think it's pretty obvious that Bracken is lip syncing.
