When long-term congressman Cam Brady (Will Ferrell) commits a major public gaffe before an upcoming election, a pair of ultra-wealthy CEOs plot to put up a rival candidate and gain influence over their North Carolina district. Their man: naive Marty Huggins (Zach Galifianakis), director of the local Tourism Center. At first, Marty appears to be the unlikeliest possible choice but, with the help of his new benefactors' support, a cutthroat campaign manager and his family's political connections, he soon becomes a contender who gives the charismatic Cam plenty to worry about.
