In a spirit of solidarity, the inhabitants of a neighborhood get together and decide to put on a show for the benefit of a homeless person. The whole neighborhood then parades to the local bistro for preparations, much to Manu's chagrin. Bertrand the boss of the pressing, Vasarelli the cop, Fanny the crepe maker, and Jules the very young musician. Bad faith is often hidden behind good feelings. It is the occasion of merry shouting sessions, but also of improbable friendships and heated discussions - It must be said that it is not easy to get along, even for a good cause, with such personalities.
