Stan has to convince the dictator of Isla Island to sign a treaty in order to get a promotion at work. When Stan meets the general and accidentally kills him, he gets Roger to pose as the leader of the small island nation. However, Roger takes his persona too far and Stan has to rescue him from an impending revolution. Meanwhile, Steve and Snot become competitive to see who can get farther with the other's mom.

When Hayley and Steve leave for their respective summers of fun, Francine looks forward to her newfound alone time with Stan. There's only one problem: Roger is still living in the attic fighting for every second of attention he can get. When Francine teaches Roger to be self-sufficient, he finally gets a place of his own. Stan fears that he will bore Francine into leaving him and cooks up a scheme to bring Roger back to the house and liven things up. Meanwhile at camp, Steve and his pals fall prey to a scheme that doesn't quite have the effect they were hoping for.
