This French family film is filled with action, animals, adventure, and suspense. The story is told from a child's viewpoint. One day, while playing in his secret tree house in the forest, 11-year old Antoine spies upon bank robbers stashing 40-million francs worth of loot. One of the robbers is the father of his newest best friend Lisa, a 10-year old Canadian visitor. Not wanting to rat on her father, Antoine instead moves the money to a different spot. Neither he, nor Lisa have a lot of respect for their frequently absent fathers. They find adults to be inherently hypocritical. Both kids do share a love of animals though. Together, they decide to run away to Biarritz, a resort town, and start spending a little money. The thieves are livid when they discover their stash is missing, particularly Max, and they try, unsuccessfully to catch the kids. Antoine is assisted by his muscular governess Clemence as he and Lisa suffer through numerous narrow escapes while spending their ill-gotten gain. - Sandra Brennan, All Movie Guide
