Previously, Martin and his friends draw the ire of Nazi zombies after unwittingly taking the gold they are after. When Martin is bitten on the arm, he removes the infected arm with a chainsaw. After returning their gold to the Nazi zombies, Martin realizes he forgot a coin. The zombies chase after him, and their commander, Herzog, tenaciously holds on to Martin's car as he flees. An oncoming truck slices off Herzog's arm, which remains in the car with Martin. After Martin passes out at the wheel and is involved in an accident, he wakes up in a hospital. The police disbelieve his wild stories about zombies and charge him with the murder of his friends. To his horror, Martin finds that a surgeon has attached Herzog's arm to his stump (believing it to be Martin's). The zombie arm goes berserk and attacks everyone within reach. After Martin kills several people against his will, he is sedated and strapped tightly to the bed. In the meantime, Herzog has his lost arm replaced with Martin's arm and begins to conscript more zombie troops by resurrecting freshly killed locals. Bobby, a young American tourist, sneaks into Martin's room when he hears rumors of a zombie attack. Impressed with Martin's zombie arm, Bobby frees Martin and tells him about the Zombie Squad, American professional zombie hunters. Before Bobby can contact them, the zombie arm throws Bobby out a window. Panicked, Martin follows and administers CPR, but the zombie arm instead crushes Bobby's chest, killing him. Martin flees the police, who believe him to be a child killer, and makes contact with the Zombie Squad - who turn out to be three nerdy friends: Daniel, Monica, and Blake - who promise to come to Norway and assist. In the meantime, they ask Martin to find out what Herzog wants. At a World War II museum, Martin meets Glenn Kenneth, the souvenir shop's clerk. After the zombie arm intimidates him, Glenn takes Martin to the museum, where they read about Herzog's history: Herzog was originally tasked by Hitler himself to wipe out
Talvik for their anti-Nazi sabotage. As Martin realizes Herzog intends to carry out his orders, Herzog and his Nazi zombies attack a group of tourists outside, and following the slaughter, Herzog has his troops arm themselves with old weapons from the museum, including a World War II-era
Tiger tank. Martin and Glenn escape death by pretending to be mannequins in the museum. While surveying the carnage, Martin accidentally discovers that his zombie arm can also raise and control the dead. When Daniel arrives, he kills the zombie Martin has resurrected; Martin demonstrates his newfound power by raising it again. Martin, Daniel, and the sidekick zombie race to find the burial ground of a group of Russian
Red Army POWs, who had been executed by Herzog during the war, as Monica, Blake, and Glenn work to slow down Herzog. Monica and Blake convince Glenn to act as bait to draw some of the zombies into a local swamp, where they kill them with pipe bombs they made from the supplies they had. After shooting at them with the tank gun several times, Herzog continues on his way, believing Blake, Glenn and Monica to be dead. Meanwhile, the others discover the graveyard, and Martin raises an entire troop of loyal Russian zombies. All converge at the town, where Martin confronts Herzog. Martin points out that they have evacuated the townspeople and thus prevented Herzog from completing his orders, but Herzog does not care and attacks them. The battle goes well at first, but the Nazi zombies eventually overpower Martin's Russian zombies after Herzog kills the Russian commander, Lieutenant Stavarin. As the Nazi zombies close in on them, Monica tells Martin to kill Herzog, as it is their only chance. Daniel attempts to take control of the Nazi zombie's tank, Martin directly confronts Herzog, and the others fight Herzog's remaining zombies. Glenn is killed by a sneaky knife attack to the throat by a Nazi zombie, and Monica and Blake are about to be overwhelmed when Daniel fires the tank gun directly at Herzog while Martin keeps him distracted. Herzog is decapitated, and the head goes far off into the further away mountains; his troops fall lifelessly to the ground, saving Monica and Blake. After they have celebrated, and having been exonerated from the murder charges as the police witnessed the zombie battle, Martin drives to the church where Hanna (his girlfriend who died during the
first film) is buried, digs up her corpse, and brings her back as a zombie. The two proceed to make out and have sex as the sidekick zombie looks on in the distance. In a
post-credits scene, the Nazi doctor recovers Herzog's severed head, which opens its eyes. ==Cast==
