When Hester is diagnosed with terminal cancer on her 40th birthday, she knows immediately what she must do: abandon her possessions and drive to California to kill her estranged father. With no friends or family tying her to the life she’s built in New York City, she quits her wildly lucrative job in corporate law and starts driving west. She hasn’t made it far when she runs into John, an environmental activist in need of a ride to different superfund sites across the United States. From five-star Midwestern hotels to cultish Southwestern compounds, the two slowly make their way across the country. But will the revelations they experience along the way dissuade Hester from her goal?
