For 300 years the planet of women awaited the coming of man. Then one arrives... He is Davis Bertram, a space-explorer. But how can he convince them he really is a man? Their legends have built Men into gods. Trying to be worthy of the Coming, the women imitate masculine virtues. They are warlike, ambitious, ruthless. Unless Davis can convince them he is a man, they will kill him for blasphemy. But if he does convince then, the Doctor-Priests will kill him to protect their own iron control of the planet...
