The past few years has seen an explosion of films about anonymous sperm/egg donation, often highlighting the most shocking result of an unregulated industry. This documentary short intends to showcase another side of the story - the lived experience of the people who resulted from a "by the book" donation. In 2018, a group of siblings who share a common sperm donor found each other via DNA testing. With 32 confirmed siblings (and growing), they have yearly reunions where they continue deepen their connection to each other and try to define what these relationships are. Blood Friends, directed and produced by one of the siblings, tells the story in their own words. It explores the complexities of nature vs. nurture, familial connections, and the bonds we form with each other.
