For the first time the 16 survivors of the 1972 Andes plane crash, who managed to live for three months by eating the bodies of their dead friends, have agreed to participate in a documentary. They are still close friends, living within half a mile of each other in Montevideo, and this compelling and sometimes disquieting film shows how for 20 years they have been unable to escape the consequences of their decision. They live beside the families of those who died, and whose bodies saved them, but they have never talked to them about the human taboo they broke and the relatives interviewed in the film continue to grieve their loss.
