20/20 continues its special edition series tonight with a discerning and shocking look at incest and those who are affected by it.

Tonight, 2020 investigates a behaviour coined as “genetic sexual attraction” (GSA) and the community who believe that their adult incestuous relationships should not be deemed illegal by law and are fighting for legal recognition of their partnerships – mirroring the early stages gay rights movement of the 70s.

The show features Ruth, a woman from London who has had a son with her father, Ron who fell in love with his sister, and Alex and Pau, a brother and sister in their early 20s who live together as an ‘ordinary’ couple in Seattle.
