The space program has finally lost its novelty, and a jaded public hardly notices another moon launch. Skilful PR men preserve the illusion that the missions have become routine. But astronaut Richard Martin can tell a different story. Of panic in deep space, of crewmen pushed beyond breaking point, of official indifference towards his own shattered life. Martin is effectively put under wraps - until the pilot of a moon capsule, loaded with nuclear weaponry goes berserk and a nightmare develops, threatening to engulf the world - a nightmare that only Martin could end.
