Starving artist Charles Dumont (Dan Duryea) takes a job as a butler in a wealthy family and winds up being indispensable to the entire household. When the family leaves for Florida, Charles decides to spend his vacation in the house, looking at all the gorgeous art and drinking the expensive liquor. He asks the chauffeur (Frank Jenks) to act as his driver as, dressed to the nines, he goes around town posing as a wealthy gentleman.
At one club, Charles sees the beautiful heiress Louise Bradford (Ella Rains). He manages to be in her box at the opera, where she has been accompanied by her sister Cynthia, her father, and her very uptight fiance. Cynthia leaves the opera with a gambler who is involved with Larry Lundie (William Bendix), a casino owner.
The family is very distressed about Cynthia's choice of boyfriend; seeing an in with Louise, Charles says that he thinks he can help. Lots of trouble ensues.
Truly delightful comedy with lots happening, including art theft, bad checks, making the perfect martini, and choosing material for suits. Everyone is top notch. Bendix, who often played a buffoon. works against type as a tough guy running a glamorous casino. Duryea isn't nasty or evil but very smooth and elegant.
All in all, fun.
