Nightmare Comes True

As they search the mountains for Dr. Gero's laboratory, Trunks tries to warn a stubborn Vegeta that the Androids are more powerful than he realizes. Meanwhile, the remaining Z Fighters arrive at North City and decide to split up in their search. Krillin is attacked by Dr. Gero, but manages to follow him to his laboratory and signals the others. While the Z Fighters try to break in, Dr. Gero activates Androids 17 and 18, who are not inclined to be under his control.
