Pitong Gatang is a barangay in Tondo where Berting Cayabyab is the barangay chairman. He holds a dark secret that no one knows about. Mariposa is an adjacent barangay where Lamberta Enriquez or Lambing, for short, is the new barangay chairwoman. She is strict, tough and idealistic. All these began to change when she met the leader of Barangay Pitong Gatang.
