Lost in Antarctica. How long can she survive? My name is Rachael, and I’m on a solo Antarctic expedition. But a month ago I lost contact with basecamp. No radio. No sat phones. Just static. Only one thing has reached me: a BBC World Service broadcast, reporting a nuclear strike on the UK. I’m safe for fourteen more days in my little hut at the bottom of the world. But I can’t stay here forever, I have to find out what’s happened. Even if there’s no one left to tell.
