Maggie's favourite tree is under threat, about to be cut down by a bureaucrat Mr. Carver to make way for a new building. Maggie and Tim and a visiting Wright Foundation student band together to save the tree. They stage a sit-in up the tree, which then becomes a focal point for everyone's protest. Nikki climbs up to protest and is joined by Mike. Then Maggie's mother climbs up to protest and so does Giles. Eventually, Mr. Carver joins the protest himself and finally the tree is saved.
