To pacify SING, HUNG promises to let him leave his job after the final trade with the drug-trafficker. However, SING is arrested by the police. Luckily, there is insufficient evidence against SING who resolutely refuses to help him anymore. Later, this determination is further strengthened when he learns that FONG is having his baby. To avoid FONG being victimized because of HUNG's evildoings, SING decides to help NAM to crush HUNG's gang. HUNG suspect SING of being disloyal to him and nearly kills SING.
