Amao is the nickname of an eight-meter-long and two-ton crocodile. The owner of the crocodile park, Bald Liu (played by Shi Zhaoqi), had no money to buy meat for the crocodile, so he sold the crocodile Amao. Unexpectedly, the buyer of Amao was Zhao Dazui (played by Lin Xue), who opened a crocodile restaurant. Before the restaurant chef hacked Amao to death, it got angry and broke free from the rope. It ran away! The eight-meter-long crocodile ran away. Amao fled to the tea garden and met Wen Yan (played by Da S) who had just been thrown away by her boyfriend (played by Pubajia). The hungry crocodile Amao swallowed the leather bag that Wen Yan carried with her. There was no meat for it in the bag, but 100,000 euros that Wen Yan had saved from making leather shoes in Italy for eight years. That was her life money. The distraught Wen Yan went to the police station to report the case, but she never thought that the person in charge of the case was the most unreliable policeman in history - Wang Buzhun (played by Guo Tao)! What's even more unexpected is that Wang Buzhun's son Wang Xiaoxing (played by Ding Jiali) is actually a close friend of the crocodile. Those who raise crocodiles, those who eat crocodiles, those who catch crocodiles, and the crocodile A Mao all fight together to create the most surprising monster movie of 2012!
