Insight: Sept 22

Keeping up a theme for SBS tonight, on Insight Alice Matthews takes a look at what happens when you discover a family secret about your DNA.

Investigating our ancestry can help us connect with relatives and explore our heritage, but what happens when your search unexpectedly uncovers a long-held family secret? Insight talks to people who’ve had to rewrite their own personal history after a DNA test or document exposed a lifetime of lies.

8:30pm Tuesday on SBS.
