Fuk Wor Triad member Ting (by Michael Tse Tin Wah) and Senior Inspector Tuen (by Pakho Chau) of the Regional Anti Triad Unit are moles that have been planted by the rival party. Within 10 years, Ting has risen through the ranks within the organization, but deep down he is fed-up with the dead-end job as an undercover cop.

He schemes to take down his secret boss, Sung (by Ken Chan) of the illegitimate Eastern Trade Company - When Fuk Wor and Eastern Trade join forces on a narcotics deal, little do the two know that it is in fact a trap set up by the masterminds, to uncover the moles’ identity. Peace and justice are long-overdue for the two, but the step towards it could prove fatal.
