Just before Passover, the corpse of a young Christian boy is found drained of blood in front of the Belz Great Synagogue in Jerusalem. The police find no murder weapon. No one claims responsibility.

Someone leaks to the Israeli press that the boy's death is a ritual murder—a blood libel. The public is in an uproar, demanding that the security forces take action immediately. Intelligence Agent Maya Rimon is convinced that the boy's bizarre murder is part of a larger conspiracy. She suspects that the arrival in Israel of three members of the Aryan Vanguard, a rightwing American neo-Nazi group, is no coincidence. She begins searching for the common link.

Maya convinces her boss, Roni Qattawi, and Police Chief Inspector, Sarit Levine, that the Aryan Vanguard are planning to stage an attack very soon. But the three of them can't agree on which site is the target. Roni and Sarit argue for the Western Wall or the Knesset. Maya deduces that the target will be Yad Vashem, Israel's national Holocaust Museum.

When the Aryan Vanguard strikes at the museum. Maya is waiting inside. Alone.
