A bomber strikes a Boston commuter train, leaving multiple people dead and many more injured. When the team is called in to help federal agents with the wreckage, they make a gruesome discovery-most of the casualties were children on a field trip. After Jordan takes the first wave of bodies back to the morgue, she begins the horrifying process of helping parents to identify their loved ones.
Meanwhile, Woody, Lu and Nigel search for evidence that may bring them one step closer to the bomber. Tensions run high in the morgue and in the field when Macy and Lu are reminded of painful losses from their past. Yet, there is no time to grieve, another bomb lies somewhere in the city ready to explode, and it is up to Woody and the federal agents to find it.
The Boston Medical Examiners office brings us Dr. Jordan Cavanaugh, who is fearless, smart and sexy. Dr. Garret Macy is Chief Medical Examiner and it is his job to keep Dr. Cavanaugh in check.
With her methods a little on the unorthodox side her relationship with Detective Woody Hoyt is constantly being tested. It is not just Medical Examiners and Detectives we also have grief counselor Lily Lebowski, criminologist Nigel Townsend, and forensic entomologist "Bug". This dynamic team takes us though the crime solving process and keeps us guessing.
