Prism Breaker depicts the collaboration between three major law enforcement agencies, namely, the Hong Kong Police Force, ICAC and Department of Justice. Although they are on different missions, but they risk their lives to deal with the evil force with the same righteousness. While investigating crime syndicate boss Tai Cho-fuk (Dominic Lam), SIP Chow Chun-kit (Bosco Wong) experiences the loss of loved ones and betrayal by colleagues. While looking into a case involving some snitch, ICAC Senior Investigator Ko Ho-yin (Kenneth Ma) faces the dilemma of turning against his family or disregarding justice. And DoJ DDPP Lau Yu-fan (Moses Chan) keeps seeking a balance between legal principles and human feelings. While playing the power game that is shrouded in mystery, these law enforcers unravel the conundrum and eventually bring the criminals to justice.
