An elderly butterfly collector (Michel Serrault) sets out on a trip with his neighbor’s eight-year-old daughter, a latchkey kid (Claire Bouanich). Their weeklong hike together through mountain valleys in search of the rare Isabella butterfly becomes a Socratic bonding experience, with the old man answering her probing questions about the distinctions between rich and poor, dreams and nightmares, and (after seeing some poachers kill a doe) life and death. Back home, meanwhile, the girl’s mother fears her child has been kidnapped, and a SWAT team awaits the presumed abductor at the end of the trail. Philippe Muyl directed this 2002 French feature, which is enhanced by Nicolas Errera’s lilting score. In French with subtitles.
