This is a charming, subtle little pre-code in which everything is implied and little actually shown.
Constance Bennet is a good girl from a good New York family and no one finds her interesting. In Paris she finds Ben Lyon, an indigent American who bums a beer from her. She hires him as a gigolo and he shows her how to be fascinating to men, using frequent kicks to the shin to encourage her education.
Lyon is particularly good in his fast-talking role and Miss Bennet is at her most charming. The two have real chemistry together and Edward Griffith directs with a gracefully moving camera under the control of the under-rated Hal Mohr. All of these combine to produce a comedy that is knowing without being cynical.
