The Morthren's power crystals have lost most of their energy. To obtain a new supply, the leaders revive beautiful alien agent Lady Seft to fulfill their need. The woman is not from their world, and is being forced to cooperate, or Malzor will allow her son to die. While Harrison is in the city to gather supplies, Seft bumps into him, and later makes mental contact with him, requesting his trust and aid.
As Harrison begins to fall in love with Seft, Kincaid has become her avowed enemy, after she and two aliens kill one of his friends while trying to locate power crystals. Kincaid, not realizing the woman is being used by the aliens, has allowed his feelings to force a showdown between himself and the protective Blackwood.
