An unexpected visitor hatches a plan that could destroy humankind unless Mulligan can act fast. But all of his cabinet — except Lucy — has abandoned him.

The cabinet heads to Camp David to solve issues with the UK in a good old fashioned peace summit — if they can survive homesickness and camp crushes.

When Zhao asks LaMarr for help fast-tracking a wonder drug, LaMarr knows just the president who can get it approved... in exchange for a shiny trophy.

The Mulligan administration announces a lottery for free housing, but there's one catch: no running water. Can the only plumber left on Earth help?

When food becomes scarce, Mulligan and Lucy go on a campaign to promote vegetables while Farrah tries to create an ethical alternative to meat in a lab.

During a heatwave, Farrah tries to prevent a power outage, Mulligan keeps the only copy of the Constitution safe, and LaMarr spends time with family.

When Mulligan learns about presidential assassinations, he changes his policies to avoid a similar fate. Meanwhile, Farrah worries she's mothering TOD.

While Farrah searches for TOD in an abandoned shopping mall, the rest of the cabinet suffers from post-boat blues — except for a repressed Mulligan.

Aboard the cruise ship, Lucy and Zhao suspect the Fun Police are up to no good. Back on land, Mulligan turns America over to the United Kingdom.

Mulligan tries to convince cruise ship passengers — and potential future voters — to join him on land, but the Thirsty Princess is just too much fun.
