Someday we will learn to overcome long distances and the nearest stars will become accessible, but the spacemen who fly at near-light speeds will sacrifice their lives, their time, for the sake of those who will wait for them there, far from Earth. For a spaceman, every flight is a time jump that forces them to live in a permanent future. One day, two such spacemen will meet a young guy, Yura, who turns out to be not at all as simple as they thought, and in an attempt to unravel his true past, they will find themselves involved in very strange adventures.
