Death by Zero

Rewind ten years and an assassin called Yim Mo, aka Yama, is living the high life.

After using Yim Mo, Kiu Sing gives him some money to make him go away.

The person in front of Yim Mo's eyes is actually Yik Lan, a female assassin from Malaysia.

Kiu Sing goes to Taiwan to look for a particular person called Pheasant.

After tendering her resignation to Kiu Sing, Heung-sin seeks compensation from Charlie.

Sum-sum agrees to go out with Kiu Sing, who fails to show up as he is urgently summoned by Charlie.

Yik Lan feels guilty when she tells Yim Mo how she used to get along with her boyfriend.

Kiu Sing catches sight of a photo of Taiwanese gangster Or Ching-hung on Yat-yung's phone.

Rewind more than ten years and Kiu Sing, Yat-fu and their chums have completed their task in Taiwan.

Nga-man and Heung-sin want to go out. But Yat-fu's bodyguard gets in their way.

Cheung-fat tells his wife Man Tin-hung to handle Yim Mo and Suk-han.

Sum-sum and Yuk-fung go to the cinema. The duo readily get along as they share a common interest.

Kiu Sing promptly comes to Heung-sin's rescue. He then carries her away from the scene.

Yim Mo brings Suk-han and Yiu-hon along to offer their apologies to Tin-hung.

Yim Mo realizes Suk-han's money problems are due to Yiu-hon's illness.

Yim Mo takes Suk-han on a pleasure trip. Some local scoundrel attacks Yim Mo as he recognizes him.

Cheung-fat wants to acquire a cinema. Some interested party, who is negotiating with the owner, just will not give in.

Heung-sin nervously explains Kiu Sing is just her boss. Sum-sum is also aware of her own feelings for Kiu Sing.

Kiu Sing arranges for Nga-man to take shelter in Sum-sum's home.
