While the party is going on, downstairs, a band of German terrorists arrive and take the entire building hostage including its employees and attempts a huge robbery. But the only one who eludes capture is New Moss Vale Cop James Bartlett who launches a one man war in an attempt to stop the terrorists and save all hostages including his wife Sarah Machel Galler.
