The third episode of the science fiction series Man From Atlantis airs on NBC, starring Patrick Duffy and Belinda J. Montgomery. Victor Buono (Batman) guest stars. 
When all electrical power fails in an 80 mile radius near the Foundation for Oceanic Research, Mark and the Cetacean crew investigate, hoping to discover whether or not the phenomenon has a natural cause. Mark stumbles across an ancient artifact known as the Hawk of Mu, supposedly a link to the lost Lemurian civilization of the vanished island of Mu. But the Hawk’s power is already being harnessed for less than peaceful purposes by Mr. Schubert, whose own daughter becomes Mark’s unlikely ally in the fight to stop him.
