Family ties don’t get much more complicated than the ones in this witty, winning seriocomic charmer. Erwan (François Damiens) is a middle-aged bomb disposal expert who finds himself facing a different kind of explosive situation when he learns that the man who raised him is not, in fact, his biological father—and that the woman (Cécile de France) he is seeing may in fact be his half-sister. What sounds like the makings of a Greek tragedy plays out with sparkling élan thanks to the clever script and sharply drawn characters—flawed, flesh-and-blood people fumbling their way through extraordinary circumstances.
