"Steve, I came back because Mark needed someone to help him and because I'm sick and tired of running and hiding and living like an insect in this giant grotesque world, you stay here but I want to go back home...."
Escaping from Kobick and his men, Dan and Mark head into a building via an air vent. At the other side of the wall they find themselves in a Lab run by giants who are working on a new guidance system capable of navigating to Earth.
Following a dispute within the group Mark decides to try and negotiate a way home with the giants who need his skills to complete their project..."
Steve, Mark and Dan discover a lab where a giant scientist is working on a guidance system which could get a spacecraft to Earth. Overhearing the scientist, Dr Franzen, say he is working to peacefully explore the solar system, Mark proposes a deal: to perfect the device in exchange for a ride back to Earth. The scientist accepts the offer, but his wife Altha secretly tips off Inspector Kobick.
