High-priced hooker Claudia Draper (Barbra Streisand) has been arrested for the murder of one of her clients. The attorney engaged by Claudia's parents hopes to cop an insanity plea so that she can avoid a trial and manslaughter conviction. But she refuses this, citing a proviso in New York law that may result in her spending the rest of her life in an institution. Against all odds, struggling lawyer Aaron Levinsky (Richard Dreyfuss) tries to prove that Claudia is not crazy and is capable of standing trial. He certainly has his work cut out for him; the violently impulsive Claudia is not only "nuts," but certifiably so. Though she has plenty of opportunity in Nuts to give out with her usual bravura Streisandisms, Streisand (who also produced the film and wrote the songs) is surprisingly restrained through most of the proceedings. And then there's that extended-monologue climax. Nuts was adapted by Tom Topor, Darryl Ponicsan, and Alvin Sargent from Topor's stage play.
