Plain Truth is a 2004 TV drama directed by Paul Shapiro, starring Mariska Hargitay, Alison Pill and Jan Niklas.
The film is based on Jodi Picoult's book Plain Truth, in which an Amish teen hides a pregnancy, gives birth in secret, and then flatly denies it all when the baby's body is found.
Katie protests her innocence on both charges, and Ellie Harrison (Mariska Hargitay), a tough and well-respected attorney, is brought in to defend her in court.
Eventually it is revealed that Katie had conceived the child by a young male academic student whom she had befriended while visiting her excommunicated brother at his college.
It is assumed by the jury and the townspeople that the baby died naturally of its weakened condition shortly after birth, and Katie is declared innocent of all wrongdoing.
