Zach and Muffin arrive at their grandmother's boarding house to help prepare for the Seder. In the meantime, "Bubbe," as she is known, finds a Haggadah given to her by her own grandmother among the Passover wares stashed in her attic. Handing it to Zach, she informs him that he will conduct the traditional Passover meal and service for her and her tenants – animated puppets and all. Little Zach shies away from the responsibility, until the Haggadah begins to speak. Aided by adorably depicted symbols on the Seder plate, it tells the story of how the Jews were freed from slavery by a reluctant Moses who had to find the courage to fulfill his God-given mission. The result is a delightful Seder led by Zach, who helps the others fulfill the central commandment of Passover: reliving the story as if they themselves made the exodus from slavery to freedom.
