Stuck in a dead-end temp position at a renowned law firm, attorney-at-law Tae-su dreams of one day landing a permanent position there. He spends each day to the fullest to reach his goal and he gets the chance of a lifetime. He's given a special job to revitalize a failing zoo. The problem is, there aren't any animals... He has exactly 3 months to do so, and with the zookeepers' help, he comes up with a brilliant idea: no one thinks there are fake animals at the zoo, so why not dress up like animals and put on shows for guests? One by one, zookeepers put on animal suits and masks and become polar bears, tigers, gorillas, sloths! The new zoo opens and Tae-su's polar bear goes viral when a video of him drinking a can of coke hits the internet! Thanks to everyone's help, the zoo with fake animals is a massive hit and Tae-su can now go back to the law firm with a permanent job. But before he leaves the zoo, he finds out what his law firm was planning with the zoo... Can Tae-su come up with another brilliant idea to save not only himself but the zookeepers and the zoo?
