7 years after the theatrical release of IN THE OPEN, Guillaume Massart presents his second feature-length documentary, DETENTION.

The film, which we are co-producing with TS Productions, will have its world premiere at Cannes Film Festival 2026, as part of the ACID programme.

"Open a door. Manage a crisis. Write an incident report.
At the National School of Prison Administration, hundreds of women and men learn the profession of prison officer.
As the classes unfold, doubt becomes increasingly rare on their faces."

With just under a month to go before the festival, count on us to tell you more very soon!
