The Secret of NIMH

The Secret of NIMH (alternatively spelled The Secret of N.I.M.H.) is a 1982 animated film adaptation of Robert C. O'Brien's book Mrs. Frisby and the Rats of NIMH. The title of the movie was later used for newer editions of the book. It was directed by Don Bluth, produced by Aurora Pictures, and released by United Artists in the summer of 1982. It was followed in 1998 by a direct-to-video Bluthless sequel called The Secret of NIMH 2: Timmy to the Rescue.

Plot
Mrs. Jonathan (Elizabeth) Brisby, a very beautiful, shy and timid field mouse, lives in a cinder block with her children on the Fitzgibbons' farm. She is preparing to move her family out of the field they live in as plowing time approaches; however, her son Timothy has fallen ill. She visits. Mr. Ages, another mouse and old friend of her late husband, Jonathan, who diagnoses Timothy with pneumonia and provides her with some medicine from his laboratory. Mr. Ages warns her that Timothy cannot go outside for at least three weeks or he will die. On her way back home she encounters Jeremy, a clumsy but compassionate crow.

The next day spring plowing begins, and though Mrs. Brisby's neighbor is able to stop the tractor, Mrs. Brisby herself knows she must come up with another plan. With the help of Jeremy, she reluctantly visits the Great Owl, a wise creature living in the nearby woods, to ask for help. He tells her to visit a mysterious group of rats who live beneath a rose bush on the farm and ask for Nicodemus.

Mrs. Brisby goes to the rats' home, where she is amazed to see their use of electricity and other human technology, as they have taken on medieval. She meets Nicodemus, the wise and mystical leader of the rats, and Justin, a kind and friendly rat who is the Captain of the Guards, as well as a dark, ambitious rat named Jenner, who plans to kill Nicodemus in order to become a leader. She learns that her late husband, along with the rats and Mr. Ages, was a part of a series of experiments at a place known as N.I.M.H. (which stands for the National Institute of Mental Health). The experiments had boosted their intelligence to human level, allowing them to easily escape. However, the rats have concocted "The Plan", which is to leave the farm and live without stealing electricity from humans. Nicodemus then gives Mrs. Brisby a beautiful red amulet that gives magical power when its wearer is courageous.

Because of her husband's prior relationship with the rats, they agree to help Mrs. Brisby move her home out of the path of the plow. Mrs. Brisby volunteers to drug the Fitzgibbon's cat, Dragon so that they can complete the move safely. Only mice are small enough to fit through the mouse hole leading to the house, and Jonathan was killed by Dragon while trying. Later that night, she successfully puts the drug into the cat's food dish, but the Fitzgibbon's son Billy catches her and convinces his mother to let him keep her as a pet. While trapped in a birdcage, she overhears a telephone conversation between Mr. Fitzgibbon and NIMH and learns that NIMH intends to come to the farm to exterminate the rats the next day. She manages to escape from the cage and runs off to warn Justin.

Meanwhile, the rats are completing the move during a thunderstorm. However, Jenner and his hesitant accomplice Sullivan, who wish to remain in the rose bush, kill Nicodemus, making it look like an accident. Mrs. Brisby arrives and tries to convince the rats that NIMH is coming and that they must leave immediately. However, Jenner is angered by her claims and attacks her. Alerted to the situation by Sullivan, Justin rushes to Mrs. Brisby's aid; a sword fight between Justin and Jenner ensues, ending with a mortally wounded Sullivan killing Jenner by throwing his dagger right at Jenner's back and saving Justin's life, as Jenner fell into the mud below, to his death.

Though the duel was over, another disaster was just beginning: the block was sinking! Now it was Brisby's turn to save the day. She suddenly realizes that her children are still in the block after hearing their voices inside. Unfortunately, the block begins to sink in the mud it landed in. Despite the best efforts of the rats, they are unable to pull it from the sinkhole and Justin pulls Mrs. Brisby out from drowning in the mud. However, Mrs. Brisby's will to save her children gives power to the amulet, which she uses to lift the house out of the sinkhole and move it to safety from the plow. The next morning, the rats have already gone to Thorn Valley with Justin as their new leader and Timothy has begun to recover. Jeremy also eventually finds "Miss Right", an equally clumsy crow, and the two fly away together.
