Christmas is supposed to be a season of love, warm feelings, and happy hearts. But with the children's constant bickering, pretty packages and a sweet smelling tree don't come close to filling the McDonald home with the true spirit of the first Christmas. Then Mum remembers an old tradition of building a soft bed for Baby Jesus one straw at a time. Each time someone secretly does something nice for another family member, he or she gets to add a single straw to the manger. Soon the children's quarrelling and negative feelings subside and the homemade crib is overflowing. But for one family member, a required act of kindness becomes more than he can take. The Last Straw is based on a true story.
