99 is incredibly close to giving birth, which is making Max nervous and unable to pay attention to his job. He spends all of his time trying to find the shortest way to get 99 to the hospital. At the same time, CONTROL is desperately trying to find the new location of KAOS HQ. It's made more urgent because Simon the Likable is coming to town to steal the Huffiker Plans from the Pentagon. Simon is unstoppable because everyone that sees him instantly likes him and will do anything for him. Max and Simon get their directions mixed up and Simon goes to the maternity hospital while Max takes 99 to KAOS HQ, Sunny Slope Sanitarium. Dr. Kruger tries to kill them there, but they escape and Max gets 99 to the correct hospital in time for her to have twins, a boy and a girl. While everyone is congratulating Max, Simon tries to escape until he runs into the one person who doesn't like him, 99's mother.

Richard Deacon (The Dick Van Dyke Show) has a cameo as a doctor.

Simon the Likable is played by noted character actor Jack Gilford.
