The husband and children of Ruby Franke -- the YouTube star serving prison time for child abuse -- speak out in the new Hulu documentary, Devil in the Family. A trailer for the docuseries shows her husband Kevin opening up about Jodi Hidlebrandt moving into their home ... and says not standing up to them about mistreating his children "eats me alive." All three episodes of Devil in the Family: The Fall of Ruby Franke streams February 27 on Hulu and with Hulu on Disney Plus.
