Eleven-year-old Martin is a basically good boy. Unfortunately each time he decides to give a hand things end in disaster. This summer, he has been invited to spend a vacation at the Hotel Nautilus by his friend Vincent's parents. This is a great place for kids with its cabin hidden among the branches of a tree they call the "baobab". But this year a holiday camp is being built nearby...
