UCOS reinvestigate the death of a wealthy financier when a psychic tells the dead man's daughter that she needs to resolve some unfinished business on her father's behalf. Deeply sceptical of Sebastian Carter's 'gift', the team set out to prove him a fraud, but Pullman struggles to dismiss him as a con man when he reveals a conflict involving her own late father. The story's resolution depends on the use of a private residence on Heron Island on the great Barrier Reef as a hiding place for the proceeds of crime.
