Samir and Maurice run a small stolen hi-fi business which one day turns out badly. They are condemned to perform work of general interest of animation. Once they have served their sentence, Chris, the neighborhood educator, offers them to participate in the concert organized by the mayor of the city for the benefit of the orphans of Radinoslic. Their performance turned out to be mediocre and ended up in a veritable fireworks display after which they found themselves behind bars. During their stay in prison, their new vocation was born: to organize a "humanitarian" concert for their benefit. Charity Business is on the way.
