Sniper LEE HO-YEUNG (Michael Tse) left the Special Duties Unit as he failed in an operation, and since then he has gradually developed personal enmity towards his co-worker and good friend KO TSUN-KIN (Eddie Cheung). HO-YEUNG turns into a yacht merchant and then becomes a president of a Firearms Association, colluding with organised crime syndicates on the sly.
