Réveillon chez Bob

On New Year's Eve in Paris, Louis Alban (Jean Rochefort) mistakenly believes that his ex-wife lives in a tower block housing a man named Bob, whom she supposedly keeps hidden from him due to abuse. As Louis tries to confront this perceived Bob, he encounters Thierry 'T.H.' Hubert (Guy Bedos), Florence, and others, leading to a series of unexpected reunions in the vast complex.
