Atrapada en la oscuridad

A woman is executed in broad daylight right outside a police station. The victim is Cristina Hidalgo, who had been missing for twenty-seven years. From that moment on, the mission of the UDEV Homicide unit—led by Inspector Tania Bilbao—is to discover where she had been all that time. Joining the team is Arturo Yani, a police officer haunted by his childhood and a ticking time bomb; he is being blackmailed by Internal Affairs into investigating Tania, who is known within the force for her unorthodox methods. They may not seem like the ideal pair to solve the case, yet that is precisely why they are the only ones capable of seeing it through to the bitter end. What neither of them suspects is that the ultimate nightmare lies hidden right beneath their feet.
