Summer, 1967: Doctors around the world rush to complete the first successful heart transplant. An ambitious surgeon gets the opportunity of a lifetime when a pair of lovers, unable to live without one another, asks him to perform the impossible. In front of a select audience of observing "scientists," the doctor races against time to keep their love alive, while a chorus of otherworldly singing nurses keep our own hearts pounding as we ask ourselves what we would sacrifice for love.
