The unfortunate boy is stricken with leukemia after being showered with radioactive poison when an airplane exploded. Laurent takes Pascal back to Paris where he and his girlfriend Catherine (Virna Lisi) and his war buddy Verdun (Andre Bourvil) try to cater to his every wish. He buys a farm tractor and with the help of the faithful Verdun steals some wolves from the Paris zoo. Father and son spend as much time as they are allowed in this sentimental family story.
