Ash is a little grey squirrel, who looks different to all the others, having been born with no tail, gets bullied and feels excluded from the tree top fun. The adults decide to build a Treetop Adventure which helps Ash to get from tree to tree. But the little grey is not the only one in the forest who looks different?! Disaster strikes one stormy night and through acts of kindness, heroism and teamwork, differences are set aside, and friendships are formed.
