Through amazing cinematography, this arresting film takes us inside the cavity of a human chest and transforms it into a strange and supernatural land. A new camera-based computer allows doctors to perform heart surgery by controlling a single joystick, and we are along for the ride. In vibrant blues and purples, veins shimmer and a steady muscle pulsates, while a tiny metal probe attempts to repair damaged vessels. What might have been a straightforward medical document is instead a transcendent, fantastic journey into the depths of the human core.  ST
