Paul Giraud is happily married to Suzanna, and together they live in a quiet neighborhood. As Suzanna notices that their new neighbors are expressive dancers with revealing outfits, she demands Paul to complain to them about their lack of morality. As Paul knocks on his neighbors' door, he finds out that the woman is an old flame, Georgette Lalle. They reunite happily, and Georgette even attempts to kiss Paul, despite being married to her jealous husband Maurice. Paul does not answer Georgette's displays of affection, and instead introduces himself to Maurice. Back at home, Paul lies about his meeting with the Lalle's, which confuses Suzanna as Maurice comes over moments later, trying to win her affection and expressing Paul's kindness. Paul overhears their flirtatious conversation, but pretends to be asleep.
