Once upon a time there was the story of a 210-year-old oak tree that became a pillar in his kingdom. This spectacular adventure film brings together an extraordinary cast: squirrels, balanins, jays, ants, field mice... All this vibrant, humming and wonderful little world seals its destiny around this majestic tree which welcomes them, feeds them, protects from its roots to its top. A poetic ode to life where nature is the only one to express itself.
