Lou Bertignac has an IQ of 160 and a good friend called Lucas who gets her through the school day. At home her father cries in secret in the bathroom and her mother hasn't been out of the house properly for years. But Lou is about to change her life - and that of her parents - for good, all because of a school project she decides to do about the homeless. Through the project Lou meets No, a teenage girl living on the streets. As their friendship grows, Lou cannot bear that No is still on the streets when she goes back home - even if it is to a home that is saddened and desolate. So she asks her parents if No can come to live with them. To her astonishment, her parents - eventually - agree. No's presence forces Lou and her parents to finally face the sadness that has enveloped them. But No has disruptive as well as positive effects. Can this shaky, newfound family continue to live together?
