Knox Goes Away

John Knox works a day-to-day job as a contract killer employed by Xavier Crane, a crime boss. He is estranged from his wife and son and dates a Eastern European immigrant named Annie, who shares his love for books. Knox is later diagnosed with a fast-moving form of dementia called Creutzfeldt–Jakob disease. He quickly makes arrangements to cash out and retire from the business. Before that, he undertakes one last job with his partner, Thomas Muncie.
