Plot: In the early 1970s Nicholas Garrigan, a young semi-idealistic Scottish doctor, comes to Uganda to assist in a rural hospital. Once there he soon meets up with the new President, Idi Amin, who promises a golden age for the African nation. Garrigan hits it off immediately with the rabid Scotland fan, who soon offers him a senior position in the national health department and becomes one of Amin's closest advisers. However as the years pass, Garrigan cannot help but notice Amin's increasingly erratic behavior that grows beyond a legitimate fear of assassination into a murderous insanity that is driving Uganda into bloody ruin. Realizing his dire situation with the lunatic leader unwilling to let him go home, Garrigan must make some crucial decisions that could mean his death if the despot finds out.
Alternative Plot: While in Uganda on a medical mission, Scottish doctor Nicholas Garrigan (James McAvoy) becomes the personal physician and close confidante of dictator Idi Amin (Forest Whitaker). Although at first Dr. Garrigan feels flattered by his new position of power, he soon comes to realize that Amin's rule is soaked in blood, and that he is complicit in the atrocities. Garrigan faces the fight of his life as he tries to escape Amin's grasp.
