Bill Conley and Hailey MacMurray emerge from different generations to spearhead a revolution in American politics. Bill, a retired military hero with a razor-sharp intellect, is appointed to complete the term of Colorado's senior US Senator. He becomes a maverick in the Senate, ignoring party politics and spearheading a nationwide independent movement. Hailey is a statuesque beauty admired as a natural leader. She quits her job as a top fighter pilot to raise her son, Adam, and excels as a foreign service officer. Hailey wins election to Congress and later joins Bill Conley as his vice presidential running mate in a daring campaign that wins the presidency, toppling the power elite from control. The Conley-MacMurray administration is wildly popular and successful. But extremists plot to defeat them.

At a crucial moment Bill's strength fades, presenting the possibility that Hailey will become the first woman president of the United States, and challenged to overcome political and international threats.
