Crime has taken over the streets of the city and an immediate answer is needed from the authorities. The National Police, in an another effort to control the huge growth in crimes such as homicides, assaults, robberies, Group (G.I.C. in Spanish), an elite group of quick and efficient reaction that has the resources and concentration of activities needed to solve these kinds of cases. Coronel Espinoza has commanded the GIC since it’s creation with impressive results but his own murder comes to show the vulnerability of those who, risking their own lives, try to protect the citizens. In absurd circumstances, Espinoza is murdered in a supermarket robbery. In his replacement coronel Monica Umaña is appointed, and aside from having to solve Espinoza’s crime, she has the huge challenge of commanding the reduced but efficient human team of the GIC and get the same or better results that her predecessor, with the added challenge that some of her subalterns do not consider her apt for the job. The challenge for Monica becomes greater when, at the suggestion of the general director of the police, she has to include major Ramon Garcia in her team, a man she had an affair with tow years earlier. The matter would not be an issue if it were not for Monica being married, with two children and knowing that the presence of Ramon at work can cause problems with her husband, and what’s worse, deep down she knows that even though she refuses to acknowledge it, she still has feelings for the major. What Monica does not know is that Ramon has similar feelings for her. Things being the way they are, colonel Monica Umaña will not only have to face and sort our her personal problems but she will also have to prove to her superiors and to her own team that she is to right woman for the job by solving, one by one, the cases that come to the GIC and whose direct members and collaborators combine different specialties and form an interdisciplinary team with of the highest quality and performance whose personal stories intertwine, aiding or complicating the solution of the cases that come to the offices of the GIC.
