The show's episodes follow each case from the initial investigation until it reaches its legal resolution.

On the heels of last year's hit special, Jodi Arias: Cellmate Secrets, the network announces the new six-episode doc series Cellmate Secrets, which revisits some of the most infamous stories of headline grabbing criminals as part of Lifetime's Summer of Secrets line up. Angie Harmon (Rizzoli and Isles) will narrate the series, which reveals new insights and information as former friends, guards, cellmates and lovers give first-hand accounts of their time with the famed felons and defendants.
 

This true-crime series unfolds murder cases shrouded in mysterious clues that detectives must focus on to unveil the killer and solve the crime.

The Detective Diaries takes us inside the investigative minds of five American detectives as they reexamine the harrowing cases that defined their careers. From hunting killers who hid in the shadows for decades, to taking on a political machine with more than blood on its hands, to reliving the same murder through three different victims in a row, every crime turns the story back on each detective, triggering memories of painstaking investigations, forcing them to come to terms with old wounds, and revealing what drives them to stand strong in the fight for justice.
