Plot synopsis: Sarah, a morose harpist in the Jerusalem Philharmonic Orchestra, is married to Abraham, the charismatic conductor of the group. They have no children. When Hagar, a young horn player from East Jerusalem joins the Orchestra, Sarah's world erupts. A unique friendship evolves between the two women. Hagar, feeling Sarah’s pain from not having children, offers to have a baby for Sarah. Ismail, born to Hagar and Abraham, is a wild and gifted pianist whom Sarah raises as her own. When Ismail discovers the true identity of his mother, his world – and that of those around him – falls apart. Harmonia maintains the unique essence of the biblical story from Genesis and adds a personal and human perspective.
