Seth (Vilma Santos) and a group of people are talked into visiting a mysterious healer due to all of them having family members with serious ailments/illnesses seemingly having no hope to be cured in the near future.
However, the old woman renowned by locals as the miraculous healer suddenly tells them she refuses to perform any more "healings" soon after their arrival.
All their ailing relatives are cured completely once Seth and the others finally convince the healer otherwise, but they did not know the healer's warning about having to repay in equal kind everything which has been taken would manifest in terrifying ways.
