The Kursican Orbital Incarceration Platform — known as "the Plat" — is the primary prison facility for Kursican, a world applying for Federation membership. When the Plat malfunctions, the da Vinci is sent to Kursican to board and repair the out-of-control orbital station. But the da Vinci crew finds itself in the midst of a political firestorm, as the malfunction is the result of sabotage by a group of political agitators — one of whom is Augustus Bradford, an old friend of Captain Gold’s. While Commander Gomez and her crack S.C.E. team try to put the Plat right, Gold must balance his duty against his loyalty to his friend — before Kursican explodes!
