The Hucksters (1947)

Victor Norman is just out of the service and looking for a job in advertising. By playing hard to get, he figures that he can get a good job and a large salary. The first thing he has to do is get a war widow to endorse Beautee Soap - a client of the Kimberly Agency. He meets with Kay Dorrance and gets the endorsement and Mr. Evans, the head of Beautee Soap is temporarily happy. Victor's job is now to work with Mr. Evans, a man who is a strict and demanding client. Everything should be rosy, but Victor, a bachelor, finds himself more attracted to Kay, a widow, than young single Jean Ogilvie.
