3A family sits at the Passover seder table, but cannot find their afikoman--the hidden matzah required to end the meal--and as a result, they are trapped at a seder that cannot end. Six months in, a wisecracking talking goat shows up at their door with bad news: Thousands of years of previous seders have accumulated underneath their seder, and their afikoman is stuck in one of them. Now the family's "wise child" must travel down with the goat through centuries of previous Passovers to find it--and to discover the questions he needs to start asking.
