Insânia

Gripped with despair after a family tragedy, forensics investigator Paula suffers a mental breakdown that results in her admittance to a psychiatric hospital headed by Dr. Schultz. Meanwhile, Paula's partner from the force tries to help her, and another patient with controversial dietary habits is also admitted.

Dr. Schultz tries to soothe Paula's concerns about her admission at the hospital, but a charismatic patient instigates the officer's distrust about what goes on there. Meanwhile, distraught with news about his daughter, Lúcia's father makes an unexpected visit to the hospital seeking answers, and Camila uncovers a clue.

Disavowed by her former allies, Paula continues her search for answers into the mysteries that surround Dr. Schultz's hospital — even as it pushes her to face her most terrifying fears. Meanwhile, Marques and Barcellos take the investigation to another level in an unusual alliance, and Rafael and Camila discover critical information about Lúcia's case.

Paula is visited by a surprising figure in a frightening dream, leaving her even more unbalanced in her struggle to distinguish reality from fantasy. Overwhelmed with his suspicions, Marques decides to go to the hospital and confront the first person he sees. Meanwhile, an encounter with a mysterious person at the Nevoa Branca cemetery brings Rafael to change the course of his investigation.

Putting aside her unease about the doctor's ulterior motives, Paula agrees to allow Dr. Schultz to analyze her dreams. Marques — increasingly convinced that something strange is going on — returns to the hospital, but a new presence tries to steer him away. Meanwhile, Rafael loses sight of the danger that his investigation has brought into his life.

Lucas makes a startling revelation to Paula, but her dreams don't paint good news for her or her allies. Marques is forced to revisit past traumas and take drastic measures to continue his investigation. Meanwhile, Rafael settles accounts with the only person who knows what happened to his daughter.

Paula must fight her better instincts when Lucas brings her to the meeting she's been waiting for her entire life. Unaware that he would be visited at his own home, Schultz and Marques go head-to-head in a confrontation that ends in tragedy.

Paula is confronted with her innermost fears on a terrifying walk alongside Lucas, who visits her perfect world in what may be a one-way trip. Trapped physically and mentally, the investigator only has Camila to turn to.
