Ella is the worst paramedic to ever ride an ambulance, yet somehow she's a "white cloud," a medic for whom everything seems to turn out rosy. She floats through her surreal existence, dodging her ambulance partner's constant insults, until she notices her chilly fingers and resurrects a man from the dead. Startled by her discovery, she turns to the morgue, but Dr. Judah Azriel, pathologist, challenges both her desire to save the world and her understanding of death.
