I could see this played out in a music video because of the way it's presented here.  The girl hypnotized by the "Magic Man's"  charm and personality (among other things), the mother's worry that her daughter will be lost to a stranger, and her pleas to her daughter to come home.  It's up to you to decide whether she returns or not.  I like that.  Rarely do songs involve the listener to actually think about the outcome for themselves.
