SAI and FU recall the past a decade ago… Back in Canada at a Thai restaurant, SAI criticized the chef about the Tom Yum Goong he made. The boss of FU, FAI was not happy and proposed to bet with SAI by racing. FAI promised to give SAI a week as to raise money after defeating him. SAI kept calling SUM in HK but he could not get in touch with his sister… SAI was back to HK and realized that his sister was hit by some critical changes.

SAI gives KIU a helping hand when she is too drunk to get back home……
