Contract Killer (1998) on Netflix

Plot summary

A wealthy ex-Yakuza boss, Tsukamoto, sets aside money to reward whoever finds his murderer, should he be killed. A hitman known as the King of Killers kills him anyway, and the $100 million bounty goes to anyone who identifies the King. Tsukamoto's grandson Eiji takes over the family and joins the hunt. Fu, a soldier, belongs to a small gang that hears of the money. Barred from the building where lawyers set the fund's terms, Fu holds off security, and his fighting draws the notice of Lo, a petty criminal after the same payout. Lo hires Fu as muscle and gives him a room in his flat, where Fu meets Lo's daughter Kiki, a lawyer unhappy with her father's dealings. Inspector Chan of the Hong Kong Security Bureau warns them off the case.
