The First 48

For homicide detectives, the clock starts ticking the moment they are called. Their chance of solving a case is cut in half if they don't get a lead in The First 48. Each passing hour gives suspects more time to flee, witnesses more time to forget what they saw, and crucial evidence more time to be lost forever.

The First 48 follows detectives from around the country during these first critical hours as they race against time to find the suspect. Gritty and fast-paced, it takes viewers behind the scenes of real-life investigations with unprecedented access to crime scenes, autopsies, forensic processing, and interrogations.
