She is a liar, selfish and extremely pushy, so much so that even one of her few friends plans a trip with another girl.

But it's all for naught and she sets off on a journey up the remaining ladder. After meeting and parting with a mysterious man, the journey turns into a journey to find something. Will Kimama-chan be able to find "something"? Will she be able to come back to earth after the climb? I wanted to make a vertical road movie", says the director. Perhaps the only one of its kind in the world, what awaits her in the sky?
