The Stranger Within, a frightening, well-done, made-for-TV thriller with a fine performance by Rick Schroder tell the story of a boy trying to convince a unstable woman that he is her long-lost son. Mare Blackburn (Kate Jackson) is an emotionally traumatized woman whose three-year-old son was kidnapped 12 years before. One day Mark (Rick Schroder) appears on her doorstep claiming to be her lost son who has escaped and returned to her. Mare is at first overjoyed then frightened when it is apparent that her "son" is a sociopathic killer. Rick Schroder shows remarkable range in this change-of-pace performance where he plays an unsympathetic and unappealing character with great energy and intelligence. The Stranger Within is a fine, frightening psychological thriller.
