On the first anniversary of the freedom fighters' victory over the invaders, Diana's trial approaches and the half-alien child undergoes experiments.
Elizabeth's transformation is complete; Diana plots to detonate a new weapon that could destroy Los Angeles.
The aliens send Donovan and Ham to a work camp where they find Robin Maxwell and Kyle Bates, and plan a daring escape.
Diana tries to brainwash Mike into thinking the war is over; Robin hides in Nathan Bates' beachhouse; Kyle is drawn to Elizabeth.
Donovan is forced to turn himself over to the enemy to save his son, but a major breakthrough in anti-alien weaponry is made.
The heroes learn of a new Visitor device that triples the speed of human `processing', while Nathan cracks down on resistance activity.
