Lotje Sodderland was an outgoing 34-year-old with a good job and a vibrant social life.

Then one night she suffered a stroke that almost killed her and left her with permanent
brain damage.

Five years later she still struggles with simple tasks like reading, yet Lotje is now on a mission to understand how the human brain works.

In this remarkable film, she meets neuroscience pioneers who have made astonishing progress in their bid to repair ‘broken brains’, and their patients, who have heart-breaking and inspirational stories.

Lotje is left wondering how much science really knows about the complex organ that makes us who we are.
