What do 200,000 Australians a month have in common? They are all
engaging in self-harm behaviour.

The Silent Epidemic, a sensitive and poignant science documentary
screening as part of SBS's Secrets of the Human Body season, seeks to
understand the mindset of those who self-injure, and explores a radical
treatment through a world-first experiment.
