Jackie Chan, Sammo Hung and Yuen Biao are the brothers who co-starred in this action comedy following Project A. The filming was done on location in Spain, with European castles becoming the main story setting. Sammo Hung also plays a private detective who is hired to find a European woman named Goliath and her daughter Sylvia. He asked Jackie Chan and Yuen Biao, who run a fast food truck, for help, and soon found Sylvia, a pickpocket, in a mental hospital and revealed her identity. It turns out that the person that Hong was commissioned to find is actually the daughter of the Earl, which involves the huge inheritance left by the Earl and her cousin's conspiracy to seize the inheritance. In the end, of course, a tough battle for a hero to save a beauty is inevitable. Although the content of the whole film is mediocre, it is still shot in a hearty and lively manner, which meets the usual entertainment needs of Jackie Chan's movies.
