German director Karin Jurschik analytically examines the phenomenon of drones and other military robots, which fundamentally changed not only the technical aspects of warfare, but also human thinking about war and peace. In the documentary the voices of drone engineers, military specialists and experts in the field of political science and moral philosophy can be heard. Then there is a scientist who teaches machines to learn, and another scientist designing artificial brain functioning, on a synaptic rather than a digital basis, just like the human brain. There is also the creator of the famous computer game Call of Duty, which was originally invented for a fictional world, but has come to reflect a reality of modern warfare. The fascinating abilities of the killing machines inevitably lead to questions of how far their development can go in conjunction with artificial intelligence.
