Thunder is a god who likes to boast about his intelligence. One day, he is reminded by his girlfriend that he has pledged his guardianship to Don, a boy he saved 30 years ago. The boy will face death on New Year's Eve and it is time for Thunder to fulfil his pledge. When Thunder arrives in the human world, he lends his magical powers to Don without Don's knowledge, causing himself to be hit with a streak of bad luck. When this happens, the Emperor of Heaven, along with the other gods, come down to the human world to arrest Thunder.
