Six fairly cocky Paris police academy-graduated newbies join the metropolitan police, to be truly trained on the job by arrogant veterans who bicker among themselves. And the rookies' private lives and backgrounds keep interfering. Kévin Laporte is a closet-gay. Macho Alex Moreno comes from a slum family. Ambitious, academically gifted Lyes Beloumi is of Maghrebinian origin. Shy Nadia Poulain is a young mother in a shaky marriage. Haughty Laura Maurier has a complex family-relationship with captain Franchard.
