Set in Great Britain in the late 1980s -- in the midst of Margaret Thatcher's controversial tenure as Prime Minister -- this drama examines the strange relationship between two siblings. Richard (Clive Owen) has given up a well-paying job in the private sector to take a position with a government agency that oversees real estate development. While Richard has always been emotionally secure and well-adjusted, his sister Natalie (Saskia Reeves) is nervous and unsure of how to deal with her life, even after marrying Sinclair (Alan Rickman), a successful financial analyst who can afford a posh home on the River Thames. Natalie and Richard don't see each other often, and their relationship has long had an odd cast to it, as Natalie often seems to flirt with her brother. One day, Richard meets Natalie and Sinclair over lunch, and Richard finds himself strongly attracted to his sister. In time, a mutual interest evolves into a full-blown incestuous affair. Natalie realizes that this sort of relationship can't go on and tries to break it off with Richard, but he becomes irrational, attempting suicide and threatening violence. While dealing openly with the sexual nature of its story, Close My Eyes also uses incest as a metaphor for moral and political irresponsibility.
