Qin Guoli, a Chinese accountant based in Great Britain, has been forcibly contracted by Maasym, leader of the terrorist organization Brothers of Vengeance, to finance his projects. After Qin had tipped off Scotland Yard, Maasym was killed in a military operation by US forces, but his son Omar has survived and now wants to get his hands on his father's money, whose whereabouts are solely known to Qin. Omar has hired the mercenary gang Arctic Wolves, who kidnap Qin and his new wife Meiwei during London Chinatown's New Year festival.
