Set in 1970 and inspired by true events, “Women in Blue” tells the story of four women who defy the ultraconservative norms of the time and join Mexico’s first female police force, only to discover that their squad is a publicity stunt to distract the media from a brutal serial killer. As the body count grows, María, whose determination to catch the killer becomes an obsession, Gabina, whose father is a renowned cop, Ángeles, a brilliant fingerprint analyst, and Valentina, a young rebel, set up a secret investigation to achieve what no male officer has been able to do and bring the serial killer to justice.
