Heidi Sloan's marriage is over, and the stress is eating her inside. A phone call to her beloved Grandmother Olivia results in what Heidi hopes will be a therapeutic visit to the old farmhouse that Olivia and her deceased husband, Matt, raised their family in.
One afternoon, while going through some old things in Gran's attic, Heidi comes across an ornate box that she hasn't seen since childhood. When she last saw it, she was a child playing in the attic with her cousin Sammy. Her grandfather took it away from her hurriedly, and, now, much like then, Gran takes the box from her again. Heidi, still curious as to the box's contents, confronts her grandmother who refuses to reveal what's inside.
Heidi's curiosity, a visit from Sammy, and some buried memories change, not only her visit with her grandmother, but her life. What will happen to Heidi? More importantly, what's inside The Box?
