Clint Eastwood directs this thriller based on true events that took place in 1920s California. Angelina Jolie stars as Christine Collins, a mother who thinks her prayers have been answered when her kidnapped nine-year-old son is returned to her. However, she quickly realises that the boy with whom she has been reunited is not in fact her son.
She must now face a corrupt police force and a seemingly immovable legal system to continue the fight to find her own son. Slandered by the press as unstable and delusional, she eventually finds an ally in activist Reverend Briegleb (John Malkovich), who helps her take on the authorities and track down her missing son.
