There are small problems everywhere, including in a Paris area bourgeois housing development. In this particular building, a motley crew tries to resolve shared co-ownership problems. Among them, a Foreign Legion colonel and his dog; an unfaithful gynecologist and his fiery nurse; a voyeuristic filmmaker and his editor in love; a Don Juan-type antique dealer; an adorable old lady and her nice son who turns into a drag queen at night; an FIFG interviewer; an unbearable opera singer; a lesbian; a deceived woman.
