While at work, Paige discovers that a 10 year-old boy in foster care has the ability to magically start fires. Upon learning that his foster parents are actually demons who are attempting to get him to use his powers for evil, she, Piper, and Phoebe try to convince him to use his powers for good. Meanwhile, Cole proposes to Phoebe now that they are no longer possessed by spirits. However, when she puts on Grams' engagement ring, she falls under its magical spell and turns into a 1950's housewife. Also, Cole goes to work with Paige at the social services office.

After getting a case of cold feet about marrying Cole, Phoebe decides to cast a spell where she brings her future, cynical self and herself when she was an innocent child to the present in order to gain some guidance as to what she should do. Meanwhile, Cole gets possessed by the Source and eventually becomes unable to resist doing his bidding. An evil demon called Kurzon attempts to align with the Seer to become the next Source and is sent on a mission to destroy the Power of Three. At work, Paige gets promoted to a social worker. However, worried that what she did in order to be promoted could be seen as a personal gain, she attempts to make things right with her co-worker that was passed up for the job.
