Once upon a time, there was a 210-year-old oak tree that became a pillar in its kingdom. This spectacular adventure film brings together an extraordinary cast: squirrels, weevils, jays, ants, field mice... This vibrant, humming and marvellous little world seals its destiny around this majestic tree that welcomes them, feeds them and protects them from its roots to its top. A poetic ode to life where nature alone expresses itself.
