After a visit to the Natural History Museum in Paris, Simon Esich is convinced that a prehistoric man has escaped from the Evolution Gallery and is meddling in his life as a modern male. He realizes that this life coach of a new type could help him regain his lost virility and win back his wife Camille, who is becoming increasingly distant since a recent promotion and the appearance of Antoine, a handsome hunk with a devastating smile.
