Save the planet!

Byeong-gu (played by Shin Ha-kyun) is a Korean youth who likes to study alien issues. Not only does he firmly believe in the existence of ET, he also attributes all the bad things on earth to aliens. Binggu's mother died in the factory. This incident dealt a heavy blow to Binggu, and his spirit was always in some abnormal state. The chairman of the factory became the alien lurking in the earth in Binggu's mind. He kidnapped the factory chairman regardless of the consequences and forced him to reveal the aliens' plot to invade the earth. However, no one believed his "nonsense". The police intervened in the kidnapping case, and Binggu was also in danger. Maybe, the hero's prediction is not wrong, but don't humans have a share in destroying the earth?
