We're in For a Bad Spell

The Stephens have to help out a man named Adam Newlarken who is doomed to be a thief if he doesn't break a two-hundred year old spell placed on his family. He ends up having to do Jackass style tricks to free him from the curse. It gets really serious when he ends up with a whole lot of money, which is coincidentially the exact amount his bank is missing that day!
