The president of a large Japanese company died of a sudden heart attack. The only legal heir to the company was a girl named Ami. Ami was on vacation in Hong Kong at the time and knew nothing about what was happening in Japan. Kumagai had wanted to acquire the company for a long time. How could Ami ruin such a good opportunity? If Ami did not sign the inheritance documents within the specified time, she would lose the qualification to inherit. Therefore, Kumagai sent a killer to Hong Kong to prevent Ami from returning home. Ami, who did not know that she was in great trouble, met amateur singer Tan Bao (played by Alan Tam) and the members of the Looser band in Hong Kong, and they got along very happily with each other. Soon, the killer arrived in Hong Kong and launched the first round of attack on Ami. The band's Fatty Cheung (played by Chen Baixiang) was caught by the killer and asked him to tell Ami's whereabouts.
