A super drill in Siberia in the 1970s opened the door to the inner world. A research institute was built in the mine. A few years later, an inexplicable explosion occurred in the research institute. The institute disappeared overnight. Unknown organisms and drugs developed in the institute are scattered everywhere. An ordinary college student in a northeastern mountain village and a North Korean special female soldier were involved in this turmoil. The pursuit of the mysterious organization, the "medicine" in the eyes of the consortium, the unknown creatures eager to evolve, a turmoil is coming quietly.
