The Halliwell girls are on the trail of a banshee demon who preys upon unhappy people. Attempting to cast a "tracking spell" to locate the miscreant, the girls miscalculate, and as result Prue (Shannen Doherty) is transformed into a Siberian husky -- and worse still, Phoebe (Alyssa Milano) becomes a banshee herself! Meanwhile, Cole (Julian McMahon) appears to be weakening in his resolve to remain human...but does this mean that his "demon" side has won? ~ Hal Erickson, Rovi
