Set in 2010, "Line Walker: The Prelude" serves as a prequel to the hit 2014 TVB drama "Line Walker". The story kicks off when a drug cartel operation in Bangkok goes catastrophically wrong, resulting in the mysterious deaths of several undercover Hong Kong police officers who reported directly to Superintendent Cheuk Hoi. Left alone and facing internal corruption within the police force, Cheuk Hoi must rebuild a new network of undercover agents to uncover the truth and find out who the black police mole is. Teaming up with Inspector Pak Ka-wai and reformed triad member Chu Chi-pan, Cheuk Hoi navigates the perilous underworld of Hong Kong and Thailand. As they cross paths with ruthless triad bosses, ambitious narcotics traffickers, and shifting alliances, the line between justice and criminality blurs. Trust becomes a luxury few can afford, and every secret agent risks not only their badge, but their very lives.
