The Charmed Ones are in a race against time when the mythological Pandora's Box falls into the hands of Katya, a shape shifting demon who intends to open the box and fill the world with all of the evils, illnesses, diseases, sorrows and toils contained within. Phoebe and Piper try to find Hope, the Guardian who can return any released evils to the box. Meanwhile, Paige's Whitelighter side starts to grow stronger and she is able to hear the Elder's call. At Leo and an Elder named Sandra's suggestion, Paige is sent to save a future Whitelighter and gets trapped in an elevator with people she has to save. She does so and returns home in time to help out. Using her new Whitelighter powers, Paige disguises herself as Hope and tricks Kataya. Paige vanquishes her, saves Hope's friend Darcy and sends her home with Pandora's Box where Hope is able to return all of the sorrows to where they belong. Paige meets with Sandra who reveals that Paige herself was the future Whitelighter she was meant to save and says that Paige has proved she can handle Whitelighter duties as well as Charmed ones. Sandra tells her that being a Whitelighter can be very fulfilling for her and suggests to Paige that perhaps being a Whitelighter is the life separate from magic she was looking for.
