After Phoebe has a premonition about an evil warlock killing Prue to obtain her powers, Prue decides to cast a spell to multiply her powers. However, it doesn't turn out like she expected and as a result, she makes multiple copies of herself. As Piper and Phoebe try to find the best way to warn Prue not fight the warlock on her own, Andy gets some rather surprising news from the medical examiner. Prue and Piper are surprised to find out Phoebe has signed up for a self defense course.

After Prue befriends a young man studying to become a priest, she soon discovers that he is half mortal, half warlock and trying his best to resist the urge to succumb to evilness and join his half-brothers to complete the triangle of evil Charmed Ones. Phoebe tries to talk Piper into dating Josh.
