"The unnamed narrator, a man, arrives at Mars after a flight by 'aeroplane.' Mars is much like Earth, and inhabited by Earth-like flora and fauna. Where it differs is in the social roles of the genders. Women occupy a place of equality; they have their own social clubs, take lovers, have children out of wedlock, and can even propose marriage to men. The protagonist gets to meet a Christ-like 'Teacher,' and compare religion on both planets."
