 While in a cave, two explorers accidentally release the powerful evil witch Tuatha, and she casts a spell killing them and sends her serpent to chase her magical wand. Meanwhile, Leo meets Piper and Phoebe, tells them that Tuatha is free and advises them that they should find a teenager called Kyle Gwideon, the seventh boy of a seventh generation, since he is the chosen one to handle the wand and destroy Tuatha. Prue coincidently gets the wand in Buckland and brings it home. Tuatha kills three hikers in the woods removing their hearts, casts another spell making the Halliwell sisters powerless, while Leo trains the coward Kyle, but the boy is afraid to face Tuatha.
