Wakonta Kapunda, 23, from Tanzania was hit by a car on her high-school graduation day four years ago.

After months of treatment, her whole body was left paralysed, but not her hopes of being a screenwriter.

She now uses her tongue to write film scripts, respond to phone calls and send texts.

Wakonta recently took part in a screen-writing class in Zanzibar, where the BBC caught up with her.
