What do you do when someone you love does terrible things? This question haunts Neshama Carlebach, daughter of Rabbi Shlomo Carlebach, a legendary Jewish musician whose melodies are sung in synagogues worldwide. Celebrated as a spiritual leader and cultural icon, Shlomo was later accused of decades of sexual abuse. DARKEST LIGHT follows Neshama as she confronts the devastating truth about her father, drawing on intimate interviews and rare archival footage. Featuring survivors, followers, and family members—including those who continue to defend him—the film examines the painful contradictions of a man revered by many and a community struggling with his legacy.
