A national volleyball player with dreams of joining paramilitary forces met with a terrible accident. Thrown off a running train. Lost a leg. But in less than two years, she was literally on top of the world. Here's the incredible journey of Dr Arunima Sinha – the world's first woman amputee to scale Mt Everest – the highest peak in the world.

She didn't stop at just that. Over the next five years, she conquered the highest peaks of five other continents – Mt Kilimanjaro, Mt Elbrus, Mt Kosciuszko, Mt Aconcagua, and Mt Vinson.
