Dave
Dave Kovic, a kindhearted man running a temp agency and a dead ringer for U.S. President Bill Mitchell, is hired by the Secret Service to impersonate the President for a brief public appearance. However, when President Mitchell suffers a massive, incapacitating stroke during an affair, his corrupt Chief of Staff, Bob Alexander, and Communications Director, Alan Reed, decide to keep Dave in the role indefinitely to prevent a national crisis and maintain their own political power. Initially going along with the charade, Dave soon begins to use his position to genuinely help people, approving bills and making decisions that benefit the common good, much to the frustration of Alexander. He also forms an unexpected bond with the First Lady, Ellen Mitchell, who initially despises her husband but grows to admire Dave's integrity and compassion. As Dave uncovers Alexander's plans to frame the Vice President for embezzlement, he devises a scheme to expose the Chief of Staff's corruption, reveal the truth about the real President's condition, and then "resign" due to a fabricated second stroke, allowing him to return to his ordinary life with a clear conscience and having made a profound positive impact on the country.
