Description: All seems well at the gleaming white city of the Atlantians, but the Source - a master brain which controls all around it - is in need of energy and Scott is singled out as the supply. With many of the original party returned to their own time, Varian, Scott and Fred find themselves caught up in the machinations of a megalomaniacal "brain in a box" called The Source, which has enslaved the inhabitants of the city of Atlantium (actually the Westin Bonaventure Hotel in Los Angeles), built by the survivors of the original Atlantis and intends to use Scott's life force to regenerate itself. The trio are aided by dissident Atlantean, Liana, who reveals that she is half alien.
