In this three-part TV miniseries sequel, the Resistance is fending off the pressing Visitors, who continue to fool the people of Earth by controlling the media, while depleting the planet of precious water and rounding up humans for food. The resistance scientists hope, hoping to find a weakness in the overpowering Visitor defenses that will help them turn the tide of the war. However, the Visitors still manage to gain the upper hand, especially when they capture Resistance leader Juliet Parrish (Faye Grant), who the scheming Diana (Jane Badler) tries to break with intense conversion techniques. Meanwhile, Robin Maxwell (Blair Tefkin) is dealing with her pregnancy from the lizard-like aliens, horrified at what kind of baby she will have. Marc Singer co-stars. Richard T. Heffron directs.
Bradford Dillman stars as Paul Grogan, a reclusive alcoholic living in a cabin out in the woods in an undisclosed part of the United States. He’s visited by a skiptracer named Maggie McKeown (Heather Menzies), who is out to find a couple of backpackers who have disappeared without a trace. Their search leads them to an abandoned Army research facility solely inhabited by a strange scientist, Dr. Hoak (Kevin McCarthy). Hoak has been keeping up the research on “Operation Razorteeth,” where mutant carnivorous piranha fish became bioweapons they can use to destroy the coldwater river systems of North Vietnam. The war ended, and the research stopped, but the scientist wouldn’t abandon it. A mishap sees the piranha drained out into the nearby river, where they begin to wreak havoc on anyone unlucky enough to be in the water with them. Joe Dante directs this Roger Corman production from a script by John Sayles.
