While covering a report for a TV animal program about stray dogs coming down from the mountains and making a mess of an apartment complex’s garbage area, they come across a mysterious man. This man, who comes to be known as the so-called “Wild Dog Man,” quickly becomes the talk of the town. He then seeks out dog trainer Lee Ji-ryong, asking him to “turn me into a person within half a month.” Will the Wild Dog Man be able to become human through Ji-ryong’s training?!
