Polly Vacher wanted to become the first pilot to complete a solo flight around the world via both Poles in a single-engine aircraft.

Her 60,000-mile voyage would take her to every continent. She prepared meticulously for two years and had garnered multifarious sponsors. However, as she took off, flanked by a Hurricane and a Spitfire, and waved off by her family and the Prince of Wales, she suddenly felt so alone. She had begun a remarkable expedition that would gain her three world records but would also see her encounter extremes of weather and emotion, kindness, obstruction and a little political intrigue.
