The 4 season of Saving Hope was broadcast on CTV from jeudi 24 septembre 2015 to dimanche 14 février 2016. It consists of 18 episodes, the first one is called "Sympathy for the Devil" and the last one "Let Me Go (2)".
When charismatic Chief of Surgery Charlie Harris at Toronto's Hope-Zion Hospital ends up in a coma, he leaves the hospital in chaos - and his fiancée and fellow surgeon, Alex Reid, in a state of shock. Along with newly-arrived star surgeon, Joel Goran, Alex races to save Harris' life. As the action unfolds, comatose Dr. Harris explores the hospital halls in "spirit" form, not sure if he's a ghost or a figment of his own imagination. Reid, along with her fellow doctors, press on to save his life and those of their other patients, as they deal with the complicated and courageous decisions that are made in their daily struggle to keep hope alive.
