The plot is as follows: a group of people (like scientists) created a time machine, because one of them is from the distant future and he knows that this very machine will lay the foundation for the creation of travel in the future. Out of interest, they sent one of them an hour ahead. There he saw that something terrible had happened. There is no one, only one of them, an invalid, crawls up to the hero and gives a video camera, where absolutely the whole hour is recorded. The protagonist goes back to his time, tells everything to the others and they try to understand what happened. Someone in black begins to follow them.
