In Hong Kong of 1969, three detectives: Director, Fugu, and Sam live a normal life. They work, eat, sleep, and live in their huge office/apartment on the second floor of an office building. They normally go out to fight crime. One case, however, changed their lives greatly. Fugu brings home a magic lamp and some other broken antiques after a tussle with two thieves at an antique shop. Thinking the lamp will grant him some wishes, he rubs it and wishes to marry his cousin, Jane. He later leaves for the US. Right after he leaves, a friendly witch named Harmy BoBo comes out of the lamp and tries to grant Sam and the Director the wishes. Only Fugu, however, can have the wishes since he rubbed the lamp first. BoBo does not know Fugu left the country, and Sam and Director does not know BoBo is a witch. BoBo decides to spend a few nights with the two detectives. She later gets robbed by the Lotus Seed Gang and leaves her twin cousins (who are originally chopsticks) behind. The twin cousins soon become part of the gang. Trouble begins at this point. While BoBo tries to stop her cousins’ criminal acts, the two detectives fight the gang. It’s not long when Fugu returns and BoBo’s reptilian boyfriend arrives. Then, more adventures follow.
