In this direct-to-video sequel to Don Bluths 1982 animated adventure The Secret of NIMH, Timmy (voice of Ralph Macchio) is the son of two courageous mice who helped save the day for the animals of Thorn Valley. While the wise Nicodemus has predicted that Timmy will some day be a great hero -- and his father expects nothing less -- the mouse is at once anxious to prove his courage and worried if he can live up to the expectations of others. Timmys opportunity finally comes when his friend Jenny (Hynden Walch) asks him to help her find her parents, who may have been kidnapped by the nefarious human scientists of the National Institute of Mental Health. The voice cast for The Secret of NIMH II: Timmy to the Rescue includes Eric Idle, Harvey Korman, Doris Roberts, and William H. Macy. ~ Mark Deming, All Movie Guide
