The Smarts' honeymoon cruise ends when their sailboat blows up. They drift to an uncharted island, which soon proves to be owned by KAOS chief Seigfried.

Max must bring a scientist, Dr. Canyon, into the CONTROL camp. His problems multiply quickly; the invisible doctor turns out to be a pretty woman whose visibility returns just as Agent 99 enters their apartment.

Max is bewildered when his young contact dies of old age.

Max goes to meet CONTROL Agent Carruthers and finds Carruthers dying of old age. The problem is that Carruthers is only 28 years old. After that, more and more agents are rapidly aging and dying, thanks to a new invention by KAOS, Dorian Gray Paint. The paint ages the real person once it's put on a picture of that person. They turn Max, 99, and the Chief into senior citizens right before they locate KAOS HQ.
