For Jackie and Martin, a dream team for ten years, all signs point to family happiness. Together with "Omma" Gisela, their closest confidante, the young couple moves from the Ruhr area to Munich. While he earns money as a well-paid trade fair builder, she hopes to have offspring soon. The well-ordered molecules of their picture book marriage are thrown into chaos by a chance acquaintance. The reason for this is Serge, who runs a creperie in the trendy district. He flirts with Jackie in an outrageously sexy way. The easy-going Breton has something daring that her "man for life" lacks. Martin doesn't initially notice how much her hormones are surging, as she travels a lot with her new job. He is absolutely sure of his wife anyway and confidently becomes friends with Serge. At a lively dinner for three, the couple learns more about the Frenchman's "savoir-vivre". To Jackie's astonishment, his free-spiritedness also appeals to her "Omma", who advises with Ruhrpott pragmatism: Once is not once - and when you get over it, your erotic curiosity goes away. However, Jackie is still hesitant to get involved with Serge's sensuality, which is no longer just for her. But Martin is not yet ready to engage in a ménage à trois without taboos.—ADR Das Erste
