In the 1950s, nomadic and flaky Caroline Wolff wants to settle down and find a decent man to provide a better home for herself and her son, Tobias "Toby" Wolff. She moves to Seattle, Washington and meets Dwight Hansen, a man who seemingly meets her goals. However, Dwight's true personality is soon revealed as being emotionally, verbally, and physically abusive to Toby while Caroline is away for a few weeks.
The marriage proceeds, and Caroline and Toby move into Dwight's home in Concrete, a small town near the north Cascades Mountains. Dwight's domineering personality is soon apparent, but Caroline remains with him, enduring several years of a dysfunctional relationship. During this time, Toby befriends a classmate named Arthur Gayle, a misfit at school and ambiguously gay. Toby wants to leave Concrete and live with his older brother, Gregory, who lives on the East Coast with their father. Arthur wants to leave because he knows he will never fit in and that there is more to life than living in Concrete. Toby plans to apply for scholarships at East Coast preparatory schools by submitting falsified school records. Meanwhile, Arthur and Toby's friendship becomes strained when Arthur accuses Toby of behaving more like Dwight. Arthur helps Toby to falsify his grade records. After numerous rejections, Toby is accepted by The Hill School in Pottstown, Pennsylvania near Philadelphia with a full scholarship.
Later, Caroline defends Toby from Dwight during a physically violent argument; they both leave Dwight and the town of Concrete.
