In 2009, a talented young American flutist named Edwin Rist broke into a British natural history museum and stole hundreds of rare bird specimens. His target wasn't jewels or gold, but beautiful bird skins collected over 150 years ago. This true story explores his bizarre crime to supply feathers to a secretive community of Victorian fly-tiers and the relentless investigator who worked to uncover the truth. It's a gripping tale about obsession, the value of scientific history, and how beauty can drive people to do terrible things.
