The Other Mother

A child claims his mother is an imposter - but only one person believes him.
Nothing is as fragile as the memory of a child...
Malone, a child barely four years old, starts to claim that his mother isn't his real mum. It seems impossible: his mother has birth certificates, photos of him as a child and even the paediatrician confirms this is her child.
The school psychologist is the only one who believes him. Desperate to find out the truth, he approaches Marianne Augresse, a police captain with better things to do with her time: hot on the heels of a a major criminal, she doesn't think the wild fantasies of a child are something she should worry about.
But what if she's wrong?
