Lee Myung-hyun and his disease control task force investigate a mutant virus that has a 100% fatality rate and kills the infected within three days. Not only must they find an antidote, they must also stop the epidemic from spreading and killing all of mankind.

In search of inspiration, rock band “Excellent Souls” — Lee Min Ki, Kang Hyeok, Yoo Han Cheol — goes on hiatus deep in the countryside. To their surprise, the village elder is none other than Kang Yoon Hee, a zippy woman who’s not only the town’s first female leader, but also the youngest. She also just so happens to be bandleader Min Ki’s first love. Amidst a rural backdrop, these scrappy rockers take stock of what stirs their passions — both musical and romantic.
