French thriller starring Romain Duris as Tom, an aspiring musician playing seedy bars in the backstreets of Paris. Torn between his music and the example of his sleazy father's life of crime, Tom seems set to follow in his footsteps. But when he meets by chance a friend of his concert pianist mother's, Tom's musical ambitions are awoken and he strives to make a better life for himself.

André Dussollier and Catherine Frot reprise their roles as the semi-retired husband and wife sleuths Bélisaire and Prudence 'Tuppence' Beresford in this comic Agatha Christie adaptation. With her husband taking a break from sleuthing duties to promote his new autobiography, a bored Prudence (Frot) wastes no time in setting up a detective agency to keep herself occupied. After taking on the case of a missing Russian heiress who has disappeared from an upmarket Swiss spa resort, Prudence, with a reluctant Bélisaire (Dussollier) now in tow, sets out to solve the mystery, which appears to revolve around the search for eternal youth.
