The wealthy businessman Chao made a will before his death, passing all his inheritance to his daughter Feifei (played by Sandra Ng) who was far away in France, and the will was kept by Chao Erye. Chao Laoye's unfilial son Qiu tried every means to modify the will, and Erye's unfilial son Dasha also wanted to obtain the will and modify it privately. One night, Lucky Star (played by Stephen Chow) was caught by Dasha when he went to Chao's house to steal. Seeing that he was good at stealing, Dasha ordered Lucky Star to help him steal the will. Qiu also accidentally discovered that the garbage picker Fung (played by Sandra Ng) looked exactly like his sister Feifei, so he ordered Fung to pretend to be his sister to defraud the inheritance managed by Erye. On the night when Erye went to welcome the fake Feifei (Fung) who came back from France, Lucky Star sneaked into the Chao family mansion to steal the will according to Dasha's instructions. Unexpectedly, the matter was exposed and was caught by Erye. In a hurry, Lucky Star lied that he was Feifei's boyfriend many years ago in an attempt to get away with it. Ah Feng, who was unaware of the situation, admitted that Lucky Star was her boyfriend for fear of being exposed. Thus, a hilarious battle for inheritance began.
