Valerie Palme (Naomi Watts) is an undercover CIA agent, searching Iraq for weapons of mass destruction. Her husband, Joe Wilson (Sean Penn) is a diplomat, who, after investigating the matter himself, finds no evidence of the yellowcake uranium on which the US have based their invasion.
When Wilson publishes a damning article in the New York Times, criticising the Bush administration's haste to declare war, an inside source retaliates, blowing Valerie's cover, and shattering her career and personal life in the process.
Based on the real-life 'Palmegate' of 2003, Bourne Identity director Liman crafts a classy and engrossing drama from Palme's own memoir, Fair Game: My Life as a Spy, My Betrayal by the Whitehouse.
