In 2018, the Chinese scientist Dr. He Jiankui crossed a Rubicon in human evolution by altering the genetic structure of embryos to produce the world’s first genome-edited babies. This controversial experiment, supported by China's government and top US scientists, led to an international uproar and swift moves by Chinese authorities to disappear not just Dr. He, but the twin girls whose genes he had edited. The documentary thriller Make People Better reveals the unknown story behind this historic scientific event from the perspectives of those who were there, includes a whistleblower’s testimony and never-before-seen interviews with He Jiankui, and depicts a world being awakened to a future where rival governments and corporations compete to make designer babies the new normal.
