The four are supposed to be helping elders that live alone. However, it all turns into their afterschool adventures. One night, when they are sneaking into one of the houses to steal from the elders, they bumped into two monsters. Consequently, they capture the little monster and start their own “investigations” and “experiments.” The four get more and more twisted as their involvement with the little monster. A cycle of never-ending bullying and torture haunt the students and the monster and nobody can get away with it.
