When the sisters discover that Cole is Belthazor, Phoebe must make one of the toughest decisions of her life: either vanquish her boyfriend or keep one of the most dangerous demons known to exist alive.

The sisters must stop a warlock from executing his plan to steal specific powers from witches in his attempt to kill every whitelighter in the world.

Prue, growing weary of her battles to save innocents and in fighting off the Angel of Death, is forced to turn her back on a dying soul, and must come to grips with her feelings towards fate and the death of her mother.

When a person who was killed right in front of Phoebe comes back from the dead to blame her, she becomes guilt-ridden and vulnerable, creating an opportunity for Zankou to steal the Book of Shadows. Meanwhile, Paige has a new charge who knows nothing about magic, and Piper and Leo attempt to plan Chris's first birthday party.
