"Captain Burton, we of the Government Authorities need the services of yourself and one other of the men in your party, for these services I am authorised to promise you the following, release of the two hostages in my custody..."
Inspect Kobick coerces the little people to help him fight an anti-Government "freedom" group planning to cause financial ruin by massive counterfeiting of giant currency.
The Earthlings find themselves trapped between two warring sides as each side prepares differing threats to the group.
Betty is held captive by Inspector Kobick who cuts a deal with Steve to locate a counterfeiting ring in exchange for her life. To find the criminals, Kobick puts the Earthlings into the city's drains system, to follow a trail of luminous ink used in printing the fake money. But the gang is tipped off, and tries to prevent this by flooding the drains with pesticide. Meanwhile, Dan, Valerie and Fitzhugh slip into Kobick's office to rescue Betty, who is held within an inescapable force field.
