Adalie is a princess of the aviation industry who grew up in the lap of luxury thanks to her parents' company, but when she loses both of her parents in an accident, she inherits the position of CEO to what used to be an industry-leading company she barely understands.

At a loss for how she will save the business, she searches her father's office for an answer, finding only an old business card from a General Electric scientist in Munich with a note written on the top: "Call if you ever want to push the limits of technology to improve your airline."
