Lana takes Archer to visit her parents in the San Francisco Bay Area with the baby in tow. She makes it clear on the flight over that she does not see him as her boy friend but rather her baby dad and does not want him referring to himself otherwise.
Archer is in for a surprise when he discovers that Lana's parents are academics who don't know she's a spy. On the spot, Sterling Archer has to make up a field of study (Medieval Slavic studies) because Lana apparently told them that he is an academic too.
There's a big misunderstanding in the Kanes' backyard hot tub as Archer mistakenly thinks that his parents want to engage in a threeway because they disrobe in front of him and think he should be nude too. Lana explains that this is what people from this area of California do.
Then the action happens: The Kane household has a break-in. The petri dishes of Mr. Kane, a microbiologist, are stolen. It's his life's work. When Archer looks through the window, the burglars fire shots at him.
Archer grabs Mr. Kane's keys with Mr. Kane and Lana in tow and goes on a high-speed chase after the assailants through the streets of San Francisco.
They finally catch the burglars and corner them in a gun fight on the street. At some point, one of the bad guys hears Lana and Archer refer to each other by name and reveals that he's none other than Slater.
It turns out that Mr. Kane's work was a matter of national security. His plans to make oil more sustainable through a special breed of algae would leave markets in chaos. Mr. Kane protests his life's work being destroyed until he checks his bank account and sees how big the payoff is and becomes pretty content.
