When Donna’s mother Eve dies, her sister inherits everything of value; all Donna gets is a list of addresses and mementos from her mother’s life, to be delivered to the significant people of her past. Her mother's dying wish sends Donna on a road trip from Texas to Arizona to scatter her ashes, make peace, uncover secrets and find understanding in the life she's been dealt. A hundred miles from El Paso, sitting in the blinding sun, Donna starts to realize she might be more than just the messenger.
