France, 1963. Since she was a child, Natacha has dreamed of freedom and adventure. Her dream has a name: air hostess. She admires the women who fly the world, with no ties, no husbands, and no cooking to do. Despite all her efforts Natacha does not match the walking fantasy that an air hostess is supposed to embody at the time. She's too... or not enough... whatever it is, she hasn't got it!

Sága is a strange, withdrawn, androgynous young girl. She has no friends and spends most of her time locked away at home. But Sága wasn't always like this; her life and personality changed dramatically at puberty when a terrible curse took hold of her. For years, she has managed to hide her dark secret from the world... But for how much longer?
