There is some dialog about breeding. The mutants are sterile, so men are needed to recreate a race of people.

A girl can read the minds of men. When someone thinks about sex, she slaps him.

Some women from the future wear dresses that end slightly above mid thigh.

A woman is swimming and is assumed to be nude, although she is never seen nude and is distorted by the water. When she gets out of the water (off screen) she wraps herself with a large towel and you can see some cleavage.

Mutants with disfigured skin attack the city residents in a violent manner, with people being killed on-screen. Some are shot and some are clubbed to death, but there is no blood or gore.

No profanity. Adult humor when a mind-reading woman slaps a man after he says, "I wish you couldn't read my thoughts."

The only smoking takes place in a hospital room (!).

The mutants are disfigured by the plague, with skin seeming to fall off their bodies. They are held in dungeon conditions, and express eagerness to kill their jailors. When the mutants do so, it is obvious they do so with great enjoyment, clubbing men to death and carrying off women.
