Yuki is a young, single mother supporting herself and her son, Haru, with a job as a bar hostess.

A middle-aged father has just married off his third daughter, but still has his nine year old son to raise whom he resents as he was unwanted.

On vacation's eve, a boy is sent to the countryside to live with his uncle after his father is imprisoned and accused of embezzlement.

The brothers of Children In The Wind deal with declining family fortunes: they must work when the father becomes sick, and eventually live with their grandfather, which means making new friends and struggling with a different environment.
