Kung-Fu Master!

Mary-Jane [Jane Birkin], along with her daughter Lucy [Charlotte Gainsbourg], hosts a party at their home where a guest, Julien [Mathieu Demy], arrives having had too much to drink. Mary-Jane tends to him, helping him recover, and what starts as a chance encounter becomes a troubling curiosity for her. Intrigued by Julien, she visits Lucy’s school to see him again and nearly collides with him in traffic, a jarring moment that foreshadows how entangled their lives will become. Later, at a café where Julien plays his favorite arcade game Kung Fu Master, the connection between the two deepens, and Mary-Jane finds herself increasingly drawn to him, even as she searches for other places where the game—an innocent detail for Julien—reappears.

As the days unfold, Mary-Jane and Julien spend time together in ordinary, day-to-day settings—shopping, wandering through town, and sharing small moments that feel unexpectedly intimate. Julien’s eagerness to be near her leads Lucy to suspect that he might have a crush on her, a notion that complicates the family dynamic and sets the stage for the central ethical tension of the story. The bond between an adult and a much younger person becomes a source of fascination, secrecy, and consequence, and the adults involved begin to wrestle with what boundaries they can or should leave intact.

The situation intensifies when Mary-Jane overhears Lucy discussing Julien’s occasional absence from school, and she visits Julien’s home to check on his homework and circumstances. In this moment, the lines between care and boundary-crossing blur, and the adults around them begin to see how far the relationship might go. Julien invites Mary-Jane to celebrate a small victory, and a kiss marks a turning point that triggers reactions from those closest to Lucy. When Lucy discovers the moment, her reaction is one of horror and betrayal, revealing how deeply the family is divided by the situation. The confrontation forces Mary-Jane to confront the consequences of her choices, while Lucy’s sense of safety and trust within her own home is profoundly shaken.

Seeking to understand and control the fallout, Mary-Jane and Julien’s connection takes them away from their familiar world to a remote island owned by the family. There, away from prying eyes, their feelings are tested against the harsh realities of age, power, and responsibility. The island becomes a charged backdrop for a relationship that cannot be sustained within ordinary social and legal norms, and its aftermath reverberates through the rest of the family’s lives. By the end of this chapter, the fallout becomes tangible: Julien’s mother contemplates legal action, and Mary-Jane faces the collapse of her daughter Lucy’s trust and custody arrangements. The film closes with a sense of unresolved distance—Mary-Jane and Julien drift apart, and the memory of what happened lingers, shaping how Mary-Jane moves forward.

Back on the city streets, Julien’s arc continues in quieter, less visible ways. He finally achieves a personal victory at the arcade, winning Kung Fu Master, a moment that becomes a bittersweet symbol of aspiration and distance from the life he shared with Mary-Jane. He asks a staff member to relay the news to Mary-Jane, but the message is not delivered as hoped, and the moment passes without the hoped-for reconciliation. Later, at his new school, peers question his romantic history, and he speaks with a tempered bitterness about his past relationship, signaling a turn toward self-reflection even as the scars of the situation remain.

Throughout, the film offers a thoughtful, restrained look at desire, unintended consequences, and the fragile balance between affection and responsibility. The performances—Lovers of the characters and their complexities—pull the viewer into a difficult conversation about consent, age, and the ripple effects such connections can have on families. While the story is anchored in intimate, human moments, it refuses to sensationalize, instead presenting a clear-eyed, morally nuanced portrayal of a relationship that challenges the boundaries of what is acceptable and what it costs those who get caught in its wake.

• Lucy [Charlotte Gainsbourg] — a central figure whose presence anchors the family drama and whose perspective sharpens the emotional stakes.

• Julien [Mathieu Demy] — the young man whose actions catalyze the events and whose path is tangled with the adults around him.

• Mary-Jane [Jane Birkin] — the adult at the center of the story, whose choices drive the narrative and its consequences.

Lou [Lou Doillon] emerges as Lucy’s sister in the broader family dynamic, and her presence adds another layer to the household’s reactions to the unfolding events. This film uses its quiet, intimate settings to examine how desire intersects with power, age, and judgment, leaving audiences to ponder where the line should be drawn and what it means to truly understand the families caught in the aftermath.
