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

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

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

The premiere will take place this 19 May at 8 pm, in the presence of the film team, at Les Arcades!
