FONG CHI-LIK (Michael Miu), a formidable businessman, is a ruthless and voracious seeker of wealth, unfortunately, he suffers from coronary heart disease, causing his life to be in imminent danger. Only through a heart transplant operation can he be pulled through his illness. Unexpectedly, his attending doctor YIU YAT-SHAN (Bosco Wong) suddenly dies in an accident, and his heart happens to be suitable as a donor organ for CHI-LIK. Having undergone the heart surgery, CHI-LIK displays an entirely different temperament, becoming an easy-going and optimistic person, who resembles the late YAT-SHAN. Such change startles YAT-SHAN's fiancée YUEN SHIU-GAT (Niki Chow) and CHI-LIK's wife TONG SIN-HANG (Joey Meng) very much, entailing a subtle change in the relationship between the three. YAT-SHAN's twin brother YIU YUET-SHAN (Bosco Wong) returns to Hong Kong for the funeral, where he gets to know everyone, on top of which he has gradually fallen in love with SHIU-GAT. In order to repay the favor with gratitude, CHI-LIK provides guidance and support to YUET-SHAN, recommending him to work in his affiliated club house. Apart from having a meteoric rise to find favor with CHI-LIK, YUET-SHAN also has a relationship with HA SZE-KA (Mandy Wong), a public affairs specialist of the club house. As YUET-SHAN respects CHI-LIK so much that he even regards the latter as his own family member, he discovers that his brother's death was not an accident.
