Film Synopsis

Martin is an energetic 11-year-old boy who has a knack of getting himself into trouble, despite his good intentions.  This year, he has been invited by his friend Vincent to spend his summer holidays with him and his family at a posh hotel in the country.  As always, Vincent intends spending the holidays in the company of his gang in a hut they have erected in an ancient tree.  Imagine the boy's outrage when he discovers that his precious tree-house, nicknamed Le Baobab, has been taken over by another gang of boys from a nearby summer camp.  When the tree-house is threatened with being demolished, the boys forget their differences and agree to work together to save it, with the help of Étienne, a strange man who turns out to be the tree's owner.  By exercising his cunning and resourcefulness, Martin finally has a chance to prove that he is capable of doing good things, if and when the occasion arises...
