 On the night of 14 November 1959, in Holcomb, Kansas, a farmhouse is broken into by the criminals Perry Smith and Dick Hickock that expect to get US$ 10,000.00. With the policy of "no witness", the murderers kill the entire family. The homosexual writer Truman Capote travels to the small town with his friend Nelle Harper Lee and decide to use the topic to write a book. When the killers are arrested, he becomes friend of Perry for his own interest and then he falls in love for him, and gets a new lawyer for them, postponing their execution until 14 April 1965.
