Every person born via sperm or egg donation potentially has multiple siblings that they have no idea about.  In this series, we follow young donor-conceived people searching for – and meeting – their unknown half-brothers and sisters – and others who are tracking down the anonymous donors who until the recent explosion of DNA websites were untraceable.  

This detective work is supported every step of the way by expert genealogists, intermediaries and a specially created social media community of their peers.  For all of the ‘searchers’ it’s an emotional journey fraught with ethical dilemmas and barriers to overcome as they pursue their vital desire to know more about where they come from and who they are.
