The grey squirrels on the south coast of Hampshire are having food problems. It's winter and there is little food - raiding the local bird table is not an option. A big seagull guards the food for the smaller birds. What can the greys do? Someone finds a video on the animal social media 'Metube' which claims that the trees growing green acorns grow them all year round - an evergreen food source! The problem is that greys aren't allowed on the Isle of Wight where the trees grow. The red squirrels and humans don't want them there either, as Rufus, red squirrel leader, tells them in no uncertain terms! The greys take to boats and try many weird and wonderful ideas to cross the great blue water that separates them. But the reds fight back big time. Who will win?
