Following her divorce after many years of marriage, Carolyn delves into her past only to discover some confusing similarities: three generations of women, three divorces, two absent fathers, two missing Christmases. While trying to establish her new, independent life, she journeys to the source, her mother's hometown in Iowa, searching for solutions to these puzzles. Her mother's trunk, filled with treasures and hidden away in a cousin's attic, holds more questions than answers, until she discovers a certain photograph that seems to hold the key to past relationships. Then, on a farewell hike through nearby Lake Macbride Park, she unexpectedly falls into a ravine and is plunged into the abyss of memory.
