A two-person interstellar medical crew responds to a long-delayed distress call claiming an imminent conflict between two planets. The ship's officer treats the summons as absurd given contemporary limits on interplanetary warfare, but their journey is abruptly interrupted when an enormous artificial force-field seizes the vessel and forces a communication protocol. The narrative follows the pair as they confront unexpected technical and political constraints, balancing professional duty, skepticism, and improvisation while untangling the situation that prompted the call and its implications for how past hostilities can affect present-day procedures.
