The Chief decides to explore the world of online dating and ends up with a stunning young woman. Concerned for their boss's safety, Max and 99 are instructed to keep an eye on him, as 99 believes he should be with someone more age-appropriate, like her own mother. However, the young woman is actually married to Dr. Paponickolini, who is secretly providing the Chief with a formula for everlasting youth. When the Chief arrives at Max's place for dinner with 99's mom, disaster strikes as KAOS mistakenly abducts her, believing she to be Dr. Paponickolini's spouse.
