Western New York, 1978: Jamie, Lewis, and Connor Thurber watch their parents' destructive dance of loving, hating, and drinking. Terrance Thurber spends this year teaching his children about the natural world: they listen to the heartbeat of trees, track animal footprints, sleep under the star-filled sky. Despite these lessons, he doesn't show them how to survive without him. And when these seasons of trying and failing to quit booze and be a better man are over, Terrance is gone. Alone with their mother the Thurber children are left to grapple with the anger they feel for the one parent who deserted them and a growing resentment for the one who didn't. Once they can leave, they don't look back. But Terrance does. Crossing the country, sobering up, and starting over has left him with razor-sharp regret. He knows that he has one last try to build a bridge, through the years, to his family.
