Harry, an old fishing buddy of Alex's, appeals to her to find out what happened to his missing son-in-law, Robbo. Harry claims he has seen Robbo's ghost and is convinced that he's been murdered by his business partner. The official explanation for Robbo's disappearance is that he ran off with a tourist backpacker, leaving behind a devastated wife. Mick Reilly is as fascinated by the revelation that Alex fishes, as he is by the report of a ghost, and he inquires about what exactly the ghost was doing. Alex and Reilly follow up on the ghost's directions and find his watch, but does this mean he's really dead? Meanwhile, Sykes and Quinn's search for the owner of a severed finger leads them to a fingerless man who denies ownership of the digit, perhaps because he is also a suspect in the armed robbery reported by a sword-wielding shop owner.
