Stuck in a dead-end temp position at a renowned law firm, attorney-at-law Tae Soo dreams of one day landing a permanent position there. One day, he is given a special job to revitalize a failing zoo. The problem is, there aren't any animals. Moreover, he has exactly 3 months to do so.
With the zookeepers' help, he comes up with a brilliant idea of having the zookeepers dress up as animals. One by one, the zookeepers put on animal suits and masks and become polar bears, tigers, gorillas, and sloths. The new zoo opens and Tae Soo'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 Soo 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 Soo come up with another brilliant idea to save not only himself but the zookeepers and the zoo?
