When teen loner and outcast Senna Black is hauled off to summer camp at Camp Whispering Pines by her parents in a desperate attempt to get her to make friends, she is expecting a boring summer of stupid camp songs, insufferable outdoor activities and bug bites. Instead, she meets a mysterious group of girls who are not just outcasts like her, but something much more.

The holiday spirit seems distant for the Boyce family until an unexpected visitor and miracle change everything on Christmas day.
