Tom and his dad are in the park testing out Tom's new invisibility suit when suddenly a van pulls up -- and kidnaps Mr. Swift!
Tom is panicked -- who would want to abduct his father? A strategy meeting is held and the FBI is called. But things get tricky when it looks like the kidnapping was an inside operation. Despite the FBI's insistence that Tom stay out of the investigation, Tom and his sister, Sandy, are determined to find their father -- and whoever is responsible for taking him, whether it's TRB, their rivals at FUG, or even the FBI itself!
One thing is certain -- Tom will test the limits of science to save his family.
