Truth matters.
In cases ripped from the headlines, police investigate serious and often deadly crimes, weighing the evidence and questioning the suspects until someone is taken into custody. The district attorney's office then builds a case to convict the perpetrator by proving the person guilty beyond a reasonable doubt. Working together, these expert teams navigate all sides of the complex criminal justice system to make New York a safer place.

When an environmental scientist, Dr. Oscar Silva, is poisoned during a global warming symposium, Detectives Cyrus Lupo and Kevin Bernard initially suspect competitors from Dr. Silva's field of study. It is soon discovered that Dr. Silva is involved in a messy custody battle with his wife’s ex-husband, Phillip Shoemaker and the focus of the investigation quickly shifts to the victim’s family. Meanwhile, the case becomes personal for Cutter as it stirs up unpleasant memories from his own past.
