They are ruled by a man named Dora (Vinay Varma), who manipulates the tribals for his own benefit. When a tribal child discovers a radio, everything changes. A schoolmaster (Samuthiraikani) enters the forest as a result of this. What changes did the tribals notice in their troubled lives after the schoolmaster’s arrival?
