In this Nova film, anthropologist and Jewish scholar Tudor Parfitt explores the possibility that a tribe from Zimbabwe, the Lemba, might be one of the lost tribes of Israel. According to the Bible, there were ten of these. While various isolated groups have claimed to be one of the tribes, there has been no real way to determine whether or not this could be true. However, with the advent of DNA testing, proof is now possible. Having had their claims rejected for many years, the Lemba cooperated with all aspects of the genetic marker test and were rewarded with positive results that they indeed had Jewish ancestry.
