In the spring of 1999, around ten graffiti artists from Toulouse and the Paris region gathered in Paris to cover a massive wall. Their goal was to create a mural titled "Third Millennium." This project was a rare feat in the graffiti world: a collective effort to produce their best work. Trumac chronicles the first two years of this group, made up of two crews: Truskool from Toulouse and Mac from Paris. Trumac takes us across France, from Marseille to Niort via Toulouse, and ultimately to the hip-hop mecca, New York. There, they meet graffiti legends like T-Kid, Daze, Cope2, Ink76, and Tats Crew.
