"We need more Louis Garrel on the cinema screen", Louis Garrel decided, and took on the job of screenwriter as well as director. And, of course, the lead role in the unpredictable crime-and-romance comedy "Innocent". Abel's young mother Sylvie (Anouk Grinberg) works in a prison at heart, teaching acting to convicts. She falls in love with a prisoner, Michel (Roschdy Zem) - and that's where the intrigue begins! The suspicious Abel does not approve of his mother's marriage and does not trust his new stepfather, who has been released. But Michel, a newly minted actor, entangles Garrel's character and his friend Clemens (Noémie Merlant) in a series of events that, for some, will end romantically.
