Uptight New York City executive, Michael Cromwell, pursues his soon-to-be ex-wife to South America and returns home with the son he never knew he had—a boy raised in a tribal village in Brazil. Armed with only his blowgun, the 13-year-old Mimi-Siku discovers that the world outside his jungle home is indeed a strange place.

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.
