Prue (Shannen Doherty) is unable to shake a tune that keeps playing in her head. Investigating this irritating phenomenon, Prue discovers that the tune is the one played on an ice-cream wagon -- and that the ice-cream vendor is methodically kidnapping little kids and transporting them to a magical alternate dimension, ruled over by the hideous, omnivorous Nothing. Meanwhile, Prue's sister Piper (Holly Marie Combs) discovers that her father, Victor (now played by James Read, taking over from Tony Denison), is somewhere in town. As it turns out, it is Victor who ends up saving the Halliwell girls from the abducted children -- who are nowhere near the "innocent victims" they appear to be.
