During the 17th Century a suspected witch is 'tested' by being dunked in water, as she goes to her death she curses the next thirteen generations of the Witchfinders family. While guest lecturing at a Boston University Derek gets involved in a series of murders/deaths that seem to involve the same family and could be connected to the long rumoured curse.

An amulet is stolen from the Legacy house. It once belonged to a cult leader and suspected sorcerer who was killed by Nick's father, also a member of the Legacy. The two brothers who stole it are the sons of Levon Zoltar, the cult leader, and they know how to release the magical powers held in the amulet. Magics that need a human sacrifice to power them!

A psychic/supernatural occurence debunker and physicist, Dr. David Praeger, is working for the army at an old railway station & tunnel in Powderwash, Colorado. The army is planning on opening a nerve weapon disposal site nearby and he is there to find out what causes the magnetic fluctations in the area. While investigating he starts seeing the 'ghost' of a signalman telling him to 'pull the switch'.

Alex finds out where he is after dreaming that he is in danger and, as much as they dislike the man's work the Legacy go to try and save him.
