Law and Order - Season 9, Episode 21: Ambitious

Season 9 seems to be quite different since a woman's child is missing, but her multiple personalities make it more difficult to know what happened to a child. Complicating the issue is the appearance of the woman's sister and the murder of their parents. On the other hand, a young woman was kidnapped, and clues to her disappearance can be found by investigating her character in a role-playing game on the Internet. Her case may also reveal evidence of an unresolved case involving the disappearance of another girl.
