It centres on the life of the entomologist Jean-Henri Fabre and his total devotion to studying insect behavior, travelling from Avignon to Paris, from Paris to his death in Sérignan. He is honoured by the French president Raymond Poincaré and his patience, obstinacy and knowledge are also recognised by Napoleon III, the publisher Charles Delagrave and the philosopher John Stuart Mill. They reach their climax in his book, Souvenirs entomologiques.
