Tanguy is 28 years old and still living with his parents. They think it's time he moves out. He doesn't, so they hatch a plan.

16 years later, Tanguy, now 44, returns to his parents' house with his daughter Zhu under his arm because Meï Lin left him. Disappointed to see their "little one" in this state, Paul and Edith do everything to give him a taste for life, without realizing that by doing so, they braid the rope to hang themselves. Because Tanguy is starting to feel good with his parents.
