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.

Danger 5 are fugitives in Metro City, wrongfully accused of kidnapping high school senior Holly De Palma. Hitler has infiltrated the police and leads the hunt for Danger 5 but little does he know that his own people are working against him: Joseph Mengele and his sinister accomplice Mr. Pedro are plotting a scheme, which involves the return of some scaly prehistoric bad-guys.

Allied Air Support surrounding China is being thrashed by Japanese Zero fighters piloted by robotic super-soldiers and, to make matters worse, Japan itself has completely vanished off the map. Danger 5 sets off in their Danger Fighters to give the Japanese some healthy competition. But even our heroes are no match for the deadly robo-pilots.

After being abducted by Mr. Pedro, Hitler is taken captive in the Vatican. A gang of surviving Nazi war criminals have formed a mutiny against Hitler and plan to hijack Catholicism in a bid for world domination. Pierre's faith is put to the test as he fights to save Christmas from the Nazis. Meanwhile Tucker retreats into a fantasy world, Ilsa encounters an old flame and McKenzie investigates Holly's newfound ability.

Hitler comes back from the dead as a zombie, and he's brought a horde of Nazis with him. As he continues his quest for Holly, Ilsa seeks revenge against Khrushchev for throwing her over, and McKenzie must pump or die when Claire's zombie head bites him.

An Allied agent has uncovered strange happenings at a Nazi-owned casino in Morocco where Hitler is rumoured to be located. After the agent goes missing under mysterious circumstances, Danger 5 is sent in to smoke Hitler out of his African cash-hole. Things get complicated when Tucker is captured by Italian submariners and Ilsa bumps into her ex-husband, Erwin Rommel, the Desert Fox.

In the first episode, Danger 5 must find out why Hitler has been abducting the world's national monuments with a squad of zeppelins. Claire poses as a dancer at Hitler's birthday party while Pierre is reunited with a lover from his past.

Captain Gibraltar, a sailor who claims to be from the lost civilisation of Atlantis, contacts Allied Command and offers salvation in the form of an invincible super weapon. Danger 5 travels to Atlantis, but they discover that Gibraltar is not as friendly as he appears.

Nazi dinosaurs are turning up all over the European front, devouring their way through the Allied war effort. Danger 5 heads to Belgium to investigate and has a series of close shaves with a trigger-happy Triceratops and a perverted Nazi Pterodactyl. When Claire traces the dinosaurs to Antarctica, Danger 5 embarks on a journey to the South Pole where they encounter the sinister Dr Mengele.

Allied troops all over Europe are spontaneously transforming into blonde haired, blue eyed, blood-thirsty Nazis. Danger 5 is sent to Switzerland to connect with Field Marshall Jenkins, whose entire platoon has recently turned Nazi. Allied Command want Jenkins home safe before he can be turned too. But things turn pear-shaped on the way when Ilsa and Jackson's drinks are spiked, buying them a one way ticket to Hitler's dungeon of occult perversions.

Danger 5 go back to World War II in an attempt to stop Hitler from changing the fabric of time. Ignoring the perils of messing with the space-time continuum, Tucker is dead set on changing the course of history for his own selfish motives while Pierre suffers the consequences. Jackson and Ilsa have a run-in with their past selves and share advice on the future. Meanwhile Hitler is holding Colonel Chestbridge hostage in his mountain lair.

In the final instalment of Danger 5, the team find themselves in an alternate future where Hitler is undisputed ruler of the universe.
