Zoey and Dan try to find out if a medical researcher who was locked in a room filled with hydrogen gas was murdered or if the incident was an accident. A psychic who claims to be receiving messages helps them and eerily is able to give them clues to the mystery. Meanwhile, Zoey bids on a silver dollar on an online auction and is frustrated when another bidder keeps topping her bids. Also, Hannah asks the psychic if she can talk to her mom.
