Martin (Vegar Hoel), the one armed survivor of the first movie, gives us a recap of that film's events, of how he's the only survivor, accidently killed his girlfriend with an ax, and how he stopped the Nazi zombies by returning their box of gold. Yet he didn't stop them. Now he's attacked in his car by the zombie Colonel Herzog and narrowly escapes, but not before the arm of the creature ends up in his car, which flips over in an accident. Martin awakens in the hospital. Of course, the police think he's gone crazy and killed all his friends. But the biggest surprise is that the doctor tells him that they were able to re-attach his arm, which isn't his arm at all. They gave him Herzog's undead appendage!
With the help of a boy he escapes from the hospital--and gets in touch with the "Zombie Squad" in America. They are a bunch of zombie fanboys, led by Daniel (Martin Starr of PARTY DOWN), who have been preparing for the inevitable zombie apocalypse. Meanwhile, Herzog and his undead soldiers descend up on the town and are able to resurrect new followers. In fact, Martin, because he has Herzog's other arm, is able to create new zombies as well.
The zombie squad shows up and finds Martin through is cell phone. Their plan is to create a zombie army of their own to defeat the Nazis, which involves resurrecting Herzog's old foe.
This is one of the best horror sequels in a long while--in fact, it's better than the first movie. There are some things in this movie I've never seen, like when the zombies are trying to siphon gas from a bus to fuel their stolen tank--with someone's intestines.
And while it's not serious, mostly a dark comedy, it respects the genre, even with its nods to EVIL DEAD and BRIDE OF THE REANIMATOR. If there's only one zombie movie you watch this year it should be DEAD SNOW 2. Highly recommended.
