Putri Cahaya tells the story of good and evil. Kindness is marked through Putri Cahaya, a sweet and kind fairy, and Shinta, a beautiful mute girl who is bullied by her stepmother and stepsisters. The Putri Cahaya always fights for good, while evil and greed are represented by the Putri Hitam and her mother, Ratu Jahat, as well as Shinta's stepfamily.

The selfish Putri Hitam wants to have a crystal ball that can open the Gate of Wrath. If the gate is opened, all difficulties and disasters will arise on earth. Meanwhile Putri Cahaya, who knows the evil of her own younger sibling, tries to continue to spread goodness on earth. They became enemies when Putri Cahaya became Shinta's guardian angel from evil attacks.
