A man searches the world for a set of mystic artifacts - 12 bronze heads of the animals from the Chinese zodiac...

The movie begins by a man telling the story of the Old Summer Palace and how it was looted in the 1800s by the British in the Second opium war. Among the treasures are bronze heads of the 12 Chinese Zodiac animals.

In the present day, the bronze heads are auctioned for over a million euros each. The main company supplying the bronze heads and other stolen relics is MP Corporation. JC (Jackie Chan), is tasked by MP Corp to find the remaining lost bronze heads, with a promise of a 10 times bonus if he can recover all of them. JC visits a man named Professor Guan, who had created 12 identical replicas for study purposes with his team of researchers, under the pretense that he is a reporter named Martin from National Geographic. When left alone, JC scans the multiple bronze Zodiac animal heads using special gloves so that his secret organisation can replicate an extremely realistic model of them. After scanning, he goes to Paris to find a woman named Coco, recommended by Professor Guan, for more information on the whereabouts of two bronze heads.
