An ex-policeman murders his wife, and sets up a complicated false trail and apparently flawless alibi in order to cover his tracks. The Chief has to find a way to crack the man's seemingly perfect defence, in order to prove that he is guilty.

An ex-thief on parole is suspected of a jewel robbery, but the Chief, who has supported him since his release, is sure that he is innocent. Of all those with the means to commit the crime however, it seems that only this man and his young cousin are likely suspects. The fate of an entire rehabilitation programme may hang on Ironside's ability to prove his friend innocent.

The Commissioner's niece makes a bet that she can sleep for one night in the master bedroom of a haunted house, then disappears without trace. The team decide to stay the night as well, but the Chief also vanishes. He finds himself alone, surrounded by ghostly figures, sinister statues and whispered messages, whilst Ed, Mark and Fran try to find out where he has gone.
