The movie has no dialogue.It is different from other movies .The world in the movie is completely different from the reality.In the movies' world ,everyone wears helmet .It seems that people in the world are highly protected and the world in the movie is so much peaceful.
The movie describes two men who also wear helmet want to make their appearance different.When they changed to human face,everyone is suprised to look at them.Maybe just like in China ,people don't like to change to maintain the peace.In the movie 's world,the helmet residents also do not like the change.
Finally,the change of two helmet men is failing and these two men decides to suicide.
To my point of view,people in the world like to mock people who act different from the normal people.And the movie mocks back to these people who mock people...
