Irène, a conniving adventuress, is under the impression that Jean, a timid waiter at a chic hotel, is a millionaire.
When she discovers what he really is, she immediately ditches him. But Jean, in love, sets out in pursuit of her and finds her on the Côte d'Azur.
He quickly goes broke, ends up adopting the lifestyle of the woman he loves and becomes an escort in a magnificent palace.
This new situation brings him closer to Irène, who finally deigns to acknowledge his existence. She then starts giving him advice and, without realizing it, becomes more and more attached to him.
