The film begins in 1927 Paris, where after the war there are many orphans. A woman named Célestine arrives at an orphanage where she is asked if she would take a young boy named Paul, who was originally from the area in Solonge where she lives. She is reluctant, and we detect that this boy features in her past, although we do not learn any more at this stage.
When they arrive back at Sologne we see that Célestine is in service to the local Count. Her husband, Borel, is the gamekeeper on the Count's estate. She introduces Paul as her cousin's son, which tells us that his real identity is best kept secret. He isn't there long before he learns of Totoche, the local poacher, characterised superbly by François Cluzet. Borel's main objective in life is to entrap Totoche in the act, this being all the more amusing since Totoche has a thing going with Célestine, who acts as an advanced warning of Borel's plans. Initially Totache wants nothing to do with Paul, but after Paul rescue's his dog from the river, the two gradually become friends, with Paul lapping up Totoche's immense knowledge of the life of the forest. As a comedy-drama this film could easily double as a nature documentary.
