C'est pas ma faute! (I Didn't Do It! )

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". The trouble is that this year a holiday camp settles nearby and that those trespassers immediately undertake to appropriate the "baobab". The war is declared..
