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.

Piper, Phoebe and Paige are shrunk to a height of five inches when they walk into a trap set by a demon named Gamil.

Wanting to protect a ten-year-old orphaned boy who is a firestarter, Piper and Leo try to hunt down the demon before he can deliver the kid to The Source. Meanwhile, Phoebe is given Gram's wedding ring by Cole, but to their surprise the ring has been cursed to transform the wearer into a traditional 1950's suburban housewife.
