The true story of a man who, on February 22, 1974, was thwarted from an ambitious plan for political assassination provides the basis for this striking psychological drama. Sam Bicke (Sean Penn) is a salesman for an office-supply company whose life is slowly beginning to unravel. Bicke's job is going nowhere, his wife, Marie (Naomi Watts), has left him, and his boss (Jack Thompson) keeps pushing self-help books on him that make a mockery of his state of mind. One of Bicke's few friends is Bonny Simmons (Don Cheadle), an auto mechanic, and together they come up with an idea for a tire shop on wheels; while neither has the money to finance the project, Bicke has learned of a program for small-business loans instituted by President Richard Nixon, which he's certain will come through for him. But Bicke is denied his loan, which dovetails with his increasing suspicion of the president's Vietnam policies and a sudden interest in the "by any means necessary" political activism of the Black Panther Party. Desperate to seem important in some way, Bicke becomes increasingly obsessed with the duplicity of Richard Nixon, until he chooses to take it upon himself to stop the president once and for all. The Assassination of Richard Nixon was the first feature film from director Niels Mueller.
