Dave Kovic, an affable and good-hearted temp agency owner, who bears a striking resemblance to U.S. President Bill Mitchell, is unexpectedly thrust into the political spotlight. Due to President Mitchell suffering a severe stroke in secret, White House Chief of Staff Bob Alexander convinces Dave to impersonate the incapacitated President in order to avoid a national crisis. Although initially hesitant, Dave agrees to the charade, stepping into the role with the intention of simply following orders and maintaining appearances until a plan can be enacted to address the situation.

As Dave becomes more comfortable in his newfound role, he begins to wield his influence for positive change, winning over both the First Lady, Ellen Mitchell, and the American public with his honesty and humane approach. His well-meaning actions, however, disrupt Alexander's ulterior motives and complicate the already delicate political landscape. Dave's growing sense of responsibility compels him to navigate the complexities of leadership while confronting the ethical dilemmas and schemes arrayed against him. Ultimately, his actions set the stage for significant developments that will impact the lives of those around him and the future of the nation.
