Suddenly, Alfonse Simms dies of a heart attack. Not wanting to lose his position in power, the president's right-hand man, Roberto Strausmann (Juliá) forces Jack to take the 'role of a lifetime' - that of the dead president, as the two men look so much alike. Jack accepts, eventually winning over the people and even the dead president's mistress, Madonna (Braga). For over a year, the two bond, and she shows Jack how the people are suffering under the dictatorship, particularly at the iron hand of Roberto (the real power behind scene) against the rebels.
