The able and brave Valerie (Naomi Wirtz Naomi Watts), a secret agent of CIA's "fight against nuclear proliferation" department, is assigned to investigate the existence of weapons of mass destruction in Iraq, but the investigation has not found any ongoing nuclear weapons program, which is very different from the results expected by many US officials. Valerie's husband Joe (Sean Penn Sean Penn), a diplomat, was commissioned to investigate whether enriched uranium had been sold to Iraq in Africa, and the result, like Valerie, found no sign of it. Joe published an editorial in the New York Times detailing his findings, only to trigger an extremely fierce war of words. Valerie was also fatally implicated. Her identity as an agent was soon leaked to a Washington current affairs reporter, and her overseas work became difficult, even endangering herself and her colleagues. Family and friends left her unbearably. Is this an accident or a deliberate frame-up? Facing the brink of collapse of her work and life, Valerie had to stand up with humiliation and fight against the powerful conspiracy behind all this with her thin body.
