The fifty years old Jean-Claude has a boring life, working in a notary office of his own and as court official evicting tenants or seizing properties, or spending the Sundays afternoons in the retirement home with his sour, rude and bitter father. When he has a minor heart problem, his doctor advises him to exercise, and Jean-Claude begins to have tango lessons in a studio in front of his office. He meets the charming forty and something years old Françoise, who is also having classes for her wedding party, and she recalls she was her neighbor in her childhood. They become close and love flourishes between them, changing their lives.
