A:
In Los Angeles in 1928, single mother Christine Collins (Jolie) returns home to discover her nine-year-old son, Walter (Gattlin Griffith), is missing. Reverend Gustav Briegleb (Malkovich) publicizes Christine's plight and rails against the Los Angeles Police Department (LAPD) for its incompetence, corruption and the extrajudicial punishment meted out by its "Gun Squad" led by Chief James E. Davis (Feore). Several months after Walter's disappearance, the LAPD tells Christine that he has been found alive. Believing the positive publicity will negate recent criticism of the department, the LAPD organizes a public reunion. Although "Walter" (Devon Conti) claims he is Christine's son, she says he is not. Captain J. J. Jones (Donovan), the head of the LAPD's Juvenile Division, insists the boy is Walter and pressures Christine into taking him home "on a trial basis".After Christine confronts Jones with physical discrepancies between "Walter" and her son, Jones arranges for a medical doctor to visit her. He tells Christine that "Walter" is three inches shorter than before his disappearance because trauma has shrunk his spine, and that the man who took Walter had him circumcised. A newspaper prints a story that implies Christine is an unfit mother; Briegleb tells Christine it was planted by police to discredit her. Walter's teacher and dentist give Christine signed letters confirming "Walter" is an impostor. Christine tells her story to the press; as a result, Jones sends her to Los Angeles County Hospital's "psychopathic ward". She befriends inmate Carol Dexter (Ryan), who tells Christine she is one of several women who were sent there for challenging police authority. Dr. Steele (O'Hare) deems Christine delusional and forces her to take mood-regulating pills. Steele says he will release Christine if she admits she was mistaken about "Walter"; she refuses.Detective Ybarra (Kelly) travels to a ranch in Wineville, Riverside County, to arrange the deportation of 15-year-old Sanford Clark (Eddie Alderson) to Canada....
