Once upon a time there was a two hundred and ten-year-old oak that was a pillar of his kingdom ... This spectacular adventure film has an unusual cast: squirrels, beetles from the weevil family, jays, ants, field mice ... All that small, bustling, buzzing and the wonderful universe depends on that majestic tree, from the roots to the branches, for nourishment, shelter and protection. A poetic ode to a life in which only nature speaks.
