Dale and Helen Brais are a marriage of farmers who subsist on what little they manage to get from their land. One stormy night, a stranger enters their home to rob and Dale kills him incidentally. The intruder is Red Burket, head of a band that is dedicated to sabotage the new railway line and there is a bounty on his head of $20,000. What seems the solution to the problems of the couple becomes the beginning of a nightmare.

Although the title (which translates as "Murders in Chicago") promises a gangster story, this is more of a murder mystery that kicks off with the seemingly accidental death of a construction worker, followed shortly after by that of a noted publisher (an uneasy-looking Eduardo Fajardo). What follows is a very confusing story in which the police, a police coroner (José Campos) and a vagrant (Fernando Sánchez Polack) who witnessed Fajardo's death embark on separate inquests on what actually happened. Meanwhile, June (María Luisa Rubio), who works as a secretary for the publishing company, is under pressure by a blackmailer (Antonio Jiménez Escribano) who has pictures of her in the sack with the deceased publisher.
