Has a protest to save a tree gone too far?

Callie's mother has chained herself to the neighbor's tree and is living inside the treehouse. She refuses to come down until the neighbor, Mr. Wilson, agrees to leave the tree standing. Soon reporters arrive, followed by an activist group called the Singing Grannies and a gang of bikers--each group adding to the chaos. Callie doesn't want to deal with any of them but she needs to figure out how to get her mother to come down from the tree so that her life can return to normal.
