They narrowly manage to escape the city, pursued by both the army and a mysterious figure called Mr. Tinker with his "goonbots".
After some hiking through the forest, they come to a highway, where they get a lift from a truck-driver named Dale to a town called Westlake (the last place from where Trixi received a letter from her brother).
Another of the townspeople helps them escape, and shows them to a secret entrance to a nearby army base (Trixi wants to search for records of where her brother may have gone).
