It's Christmas in the 1980s. Adolf Hitler is alive and has two Yuletide wishes: Danger 5 dead... and the world under his Christmas tree.

Hitler has infiltrated a high school in the American mid-west in search of a female senior student. His motives are unknown. Danger 5 are forced to go undercover and back to school, where Tucker’s teaching skills are pushed to the limit, Pierre’s coolness is put to the test and Jackson is hunted by a ruby-eyed wolf man with a machine gun and a grudge.
