The Systems Union is the largest power in the habitable zone, inhabited by people from the ancient Earth. The conflict between neighboring states has turned into a large-scale war, creeping toward Prime, the capital of the Union. A war is coming - everyone against everyone. The military is strengthening the fleet, intelligence is sending a special team on a secret mission, and a smuggler who accidentally finds himself among the expedition members dreams of saving only his own skin, and not the entire galaxy. Prime's navy is trying to stop the invasion and suffers losses in the battles, because the enemy has an unexpected trump card - black ships. No one knows where these ships, which became the main striking force of the unexpected invasion, come from. It is unknown what their crews want, why they destroy everything in their path. And why in the emptiness of space, on emergency waves, the dying whisper: “Don’t let them get close.”
