To fight the enemy, she must become one of them.

Israel, 1956: Jewish teacher Rachel Stein rather unexpectedly meets an old friend at the kibbutz. It brings back memories of her experiences in the Netherlands during the war, memories of betrayal. In September 1944, Rachel's hiding place is bombed by Allied troops; she makes contact with a resistance member and joins a group of Jews to be smuggled across the Biesbosch to the freed South Netherlands. Only Rachel escapes a massacre by patrol Germans, and is rescued by a resistance group under the leadership of Gerben Kuipers, whose son is captured trying to smuggle weapons. Kuipers asks Rachel to seduce SS-hauptsturmführer Ludwig Müntze, a mission that she will soon learn that the boat attack wasn't a coincidence.
