A large shadow drifts through the town of Abingdon in the magical hours between night and day. Abbi, a young wolf pup, and her friends Daniel, Crow, and Butterfly, hear that the Screen Head leader Glow has rebooted. Will he try to steal the Wolf Crystal again?
The Crystal is losing power. Is it Glow and the Screen Heads or a new threat in the form of a great shadow?
The Shadow Wolf emerges and spreads fear and distrust among the wolf pack. Abbi tries to convince her pack that her friends are not a threat, but the suspicions and lies spread by the Shadow Wolf are.
With the help of a wise-talking lightning bug named Sparky and the beautiful ghost of a 1920s flapper named Della, Abbi and her friends must team up with Glow and the Screen Heads to save the Wolf Crystal and the pack from the Shadow Wolf.
