Yann, a cook, and Nadia, a waitress and mother of 9-year-old child, decide to risk everything on the purchase of a restaurant.

To bail them out, Nadia has to take a job in Canada, while Yann is forced to stay behind to save the restaurant. Together, he and the child confront a relentless avalanche of creditors, an uncaring system and the daily grind from which there is no respite… Yann finally understands that his only chance of salvation lies in joining his lover – as well as reuniting mother and child – by following Nadia to Canada and a better life.

Denne gangen står mesterdetektiven ansikt til ansikt med sin største fiende, professor Moriarty, mens han reiser i Europa sammen med sin trofaste følgesvenn for å stanse mesterforbryterens planer for verdensherredømme.
