Life or Death: Medical Mystery investigates the science behind extraordinary real-life medical stories and reveals the unseen mysteries of the human body that lay hidden beneath the skin. This step-by-step, physiological narrative of patient rescues will immerse you in stories that begin as events outside of the human body and progress inside; seeing patients teeter on the brink of death. Witness the story of the human body as we follow each patient, including first-person interviews with those who were there, to find out if the doctors' interventions would eventually kill or cure. For our victims, time is not on their side. The doctors' best efforts may not allow them to see the problems that lay beneath the surface… but the audience will. With the help of biological CGI, we'll follow the journey of each patient during these life and death decisions. With skill and a bit of good luck, medical teams can sometimes solve a mystery illness right from the start; but is the first and immediate diagnosis always right?
