Antonio Escales

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.

Roberto decides to ask for permission at the office because he suspects his wife has a lover and wants to catch her. A friend of the protagonist offers to investigate the woman with the intention of giving sufficient evidence of thedeception. However, he soon discovers that his wife knows his plans.
