The Secret of NIMH is a 1982 animated film directed by Don Bluth in his directorial debut. It is an adaptation of Robert C. O'Brien's 1971 children's novel Mrs. Frisby and the Rats of NIMH. The film was produced by Aurora Pictures and released by United Artists. While released to critical acclaim, The Secret of NIMH was also a moderate box office success. The film was followed in 1998 by a direct-to-video sequel called The Secret of NIMH 2: Timmy to the Rescue, which was made without Bluth's input or consent.

Mrs. Brisby (Elizabeth Hartman), a shy and timid field mouse, lives in a cinderblock with her children in a field 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 (Arthur Malet), another mouse and old friend of her late husband, Jonathan Brisby, 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 (Dom DeLuise), a clumsy but compassionate crow.

The next day Mrs. Brisby is awakened and horrified to discover that Farmer Fitzgibbons has started spring plowing early. Although Auntie Shrew (Hermione Baddeley) is able to disable his tractor, Mrs. Brisby knows she must come up with another plan. With the help of Jeremy, she visits the Great Owl (John Carradine), a wise creature living in the nearby woods, to ask for help. He tells her to visit a mysterious group of rat who live beneath a rose bush on the farm and ask for Nicodemus.

Mrs. Brisby enters the rose bush and makes her way down to the rats' home, where she is amazed to see their use of electricity and other human technology. She meets Nicodemus (Derek Jacobi), the wise and mystical leader of the rats, and Justin (Peter Strauss), a kind and friendly rat who is the Captain of the Guards, as well as a ruthless, power-hungry rat named Jenner (Paul Shenar). From Nicodemus she learns that many years ago her late husband, along with the rats and Mr. Ages, were once part of a series of experiments at a place known as NIMH (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 an amulet called 'The Stone', that gives magical power when its wearer is courageous.

Jenner has not been a contender in any CBUB matches.
