Give back. Hip hop tells one of its many little-known stories here: transmission. This documentary is about the rise of artists who, alongside their stage life, wanted one day to develop an activity that would allow them to share and give to their community. Through intimate portraits, the spectator will thus discover how an association from Rennes has been able to set up a sustainable hip hop festival over the years and how some American rappers and / or producers manage to combine their artistic life and their life professional, both linked to their community. This film pays tribute to all these enriching actions that make hip hop a noble and benevolent culture.
