It all began when Arunima Sinha was 24. She was a keen volleyball player and had won a place on the Indian National Team. She was on a train, travelling from her home in Uttar Pradesh state to the capital Delhi to take up a job which would allow her to compete and earn money at the same time when a terrible train accident happened. She lost her leg, but didn't give up hope. Instead she developed an incredible ambition; to climb the world's highest mountain. And she made it.
