Set in 2043, humanity stands on the brink of advanced interstellar discovery, with the development of faster-than-light travel leading to the exploration of uncharted cosmic realms. Amidst these achievements, the Interstellar Security Command (ISC), a covert organization, monitors and protects Earth from potential extraterrestrial threats.

The story begins with ISC detecting an anomaly near Alpha Centauri—an unknown, cigar-shaped object they name the "Dark Horizon Anomaly." Commander Lawson dispatches Agent Mac to intercept the object as it changes course towards Earth. Mac’s mission reveals that the anomaly is alive and conscious, a bio-organic entity emitting a psychic signal. Through a surreal mental connection, Mac sees visions of civilizations devoured by a conscious black hole—a cosmic predator seeking new worlds.

Back at ISC headquarters, Mac debriefs with Commander Lawson and Dr. Ellis, who conclude that the anomaly poses a catastrophic threat to Earth. Their briefing is interrupted by a translated message from the entity itself: “Earth! Finally…” With this revelation, Commander Lawson resolves that ISC will be humanity’s last defense, committed to protecting Earth from extraterrestrial forces lying in wait.

The episode ends on a tense note, with ISC’s mandate clear: confront the unknown lurking beyond the stars and guard Earth against the mysteries—and dangers—of the cosmos.
