The big day arrives for Smart and Agent 99, but almost without Smart as he is sidetracked by a bizarre case.

Smart wears a new blazer given to him by a Chinese merchant, Lin Chan. Smart, however, isn't aware he posses a weapon in the blazer, and is mystified as object disappear around him.

When Agent 99 is caught without dessert, she gratefully accepts chocolate mousse from her solicitious neighbor Naomi Farkas. Naomi and her husband Emil are secret KAOS agents who hope to photograph some papers the Chief has with him.

Smart and 99 pose as a flamenco dancer and a seedy doctor to fool KAOS as both search for hidden gems in Mexico.

The Chief takes up computer dating and winds up dating a gorgeous young woman. The Chief's boss (unseen) orders Max and 99 to follow the Chief to make sure that this romance is not a security risk. 99 also thinks that the Chief should be dating someone more his age, like her mother. The young woman is actually the wife of Dr. Paponickolini, who is giving the Chief a secret formula for eternal youth. The Chief arrives at Max's apartment for a dinner date with 99's mom but instead KAOS shows up and kidnaps 99's mother, thinking she's the wife of Dr. Paonickolini.

Max tries to test his and agent 99's relationship by dressing up like the king. In the mean time, the real king is kidnapped by KAOS. It is up to Max to rescue him.

Dr. Erick Zharko and his assistant Bruce wire Max and 99 to a Dr. Frankenstein-like apparatus. Zharko figures that a jolt of his specially controlled electricity will shock Max and 99 into a five year sleep.

Wheelchair bound mastermind Leadside is caught in a robbery by Max and announces a three-part plan. Phase one, he will escape from Max. Phase two, he will destroy CONTROL. Phase three, he will kill Maxwell Smart. After Leadside follows through on Phases One and Two, Max holes up in his apartment, vowing "Leadside will only complete Phase Three over my dead body." This is one of my favorite episodes and Ronald Long is brilliant as Leadside. "My mother gave me Norman." The wheelchair in the back of the truck bit is still side-splittingly funny.

When KAOS plans to destroy California by smuggling into the country dolls secretly containing the ingredients for the most powerful explosive known to man, Max and The Chief enroll in Miss Valerie's School For Expectant Fathers, convinced that it is a KAOS front.
