She gets in contact with a man from the resistance and joins a group of Jews who are to be smuggled across the Biesbosch by boat to the freed South Netherlands. Germans from a patrol boat murder them all however. Only Rachel is able to escape. She is rescued by a resistance group under the leadership of Gerben Kuipers.
