In an attempt at earning some money to buy roller blades, Sabrina takes a job babysitting a little boy. However, when she is trying to calm him down, she inadvertently casts a spell which turns him into a man.

Sabrina is forced to attend a family affair on Halloween, so she sends a clone of herself to a party she was supposed to attend. Unfortunately, the simple-minded clone agrees with everything anyone suggests, which eventually leads to her streaking through Harvey's backyard. Meanwhile, the real Sabrina tries to ditch her snobby cousin Marigold and her bratty daughter Amanda (Emily Hart), and later gets a heartwarming surprise when she discovers that as a witch, she can talk to a deceased loved one for an hour on Halloween night.
