Faced with her first national crisis - the death of nine DEA agents in Latin America - Mackenzie shows strength and resolve in dealing with a corrupt leader. Meanwhile, Nathan Templeton is approached by an ambitious congressman who served with Mac's Vice Presidential candidate, Warren Keaton (Peter Coyote), and is eager to divulge potentially damaging info in an effort to derail his nomination. Mac's teenage twins resume public school, only this time it's complete with secret service detail and press spectacle, and while popular Horace welcomes the attention, shy Rebecca finds it overwhelming.

All eyes are on Mackenzie Allen as she hosts her first official summit with the Russian President - which is threatened to be overshadowed by Nathan Templeton's plan to engineer a series of cabinet resignations to coincide with the summit. Templeton goes after Mac with a vengeance, vowing to run - and win - against her in the next presidential election. Meanwhile, as First Gentleman, Rod must host his first state dinner for the Russian President and his wife.
