Jisung, Hyunjin, San, Hongjoong, Jongho, Changbin and Mingi had been best friends since childhood. They all were neighbors in a small town next to Busan.
Their teacher in high school gave them an assignment to explore the forest next to the town. They never were in the forest before and didn't know the beauty of it.
Another thing they never knew, there were a reason why their parents never took them to the forest. In the forest there were creatures. Dangerous creatures.
