Maldonne (2006)

Juliette is a wheelchair-bound nine-year-old who sees life as one big card game. She thinks it is her fault that her father abandoned her mother, Sandrine, when she was diagnosed with myopathy as a child. So when Juliette and her mom move into a new house, she decides she' s personally going to find her a new man. Juliette picks the writer next door to be his mother's new deal. Unfortunately not only does this reluctant player prove to be a child- hating bachelor, but his brother happens to be Sandrine's employer and landlord - who wants more than just gratitude from her.
