Blind boy can see
 

This is incredible. A 17 year old boy had his eyes removed due to cancer when he was 3. But he taught himself echolocation and has remarkable capabilities. The documentary covers his abilities as well as social aspects and challenges he faces.

It's about 48 minutes, in 5 parts:
