https://www.bbc.co.uk/news/av/world-us-canada-49390016/my-mum-s-meeting-my-dad-for-the-first-time Fancy waking up one morning and finding out that you have at least 19 half-siblings or diblings as they call them. The US children produced through sperm donation are now becoming young adults and are starting to look for their half brother and sisters. The girl in the film is followed as she meets some of them. At the end, she meets her father for the first time. I found it a very emotional watch.
