"This film documents an event that has never taken place – man's first encounter with intelligent life from space". We've been fantasizing about an extraterrestrial visit for decades, but what would happen if it actually took place? How would we cope? Should we be afraid? These and many other questions are addressed in this philosophical film about a hypothetical initial contact with aliens. Scientists and space affairs specialists at the UN and NASA and in the British government cooperate in this cinematic simulation of the undoubtedly exciting meeting between extraterrestrial life and humanity. The interviewees speak directly to the unknown entities as if they've already arrived. From their own fields – politics, theology, sociology, biology or space science – they ask probing questions. What are you doing here? Do you have a sense of right and wrong? Do you carry bacteria that could make us sick? Are we hazardous to your immune system? Information specialists in the British government show how a first summit in this situation could go. How do you inform the public? Will countries work together? Is there a danger involved? Above all, the alien visit raises questions about the relation between our own history of exploration, colonization and warfare, and the expectations with which we approach the unknown. This is a journey beyond terrestrial perspective, revealing the fears, hopes, and rituals of a species forced not only to confront alien life forms, but also its own self image.
