After being repeatedly misled by the terrorists and failing to track them down, fellow Deputy Commissioner Sean Lau (Aaron Kwok) believes Lee is acting too rashly, due to one of the five abducted policemen being his own son, Joe Lee (Eddie Peng). After consulting with superintendent Vincent Tsui (Chin Kar-lok) and Albert Kwang (Gordon Lam), who both believe Lee is taking measures too extreme, Lau relieves Lee of his command and assumes command of Operation Cold War.
