Burt and Rachel Markham are ordinary small business owners of a seed & feed store in a small Kansas farming and ranching community. Many years before, as young university graduates eagerly anticipating exciting overseas employment, a lifetime in Kansas was the furthest thing from their minds, particularly Rachel who was raised overseas and dreamed of going back. By July 2013 their twin 18-year old daughters, having graduated high school several months before, go east to attend a university. Burt and Rachel settle into their new life of an empty house and a predictable and unchanging routine that threatens to stretch far into the future. One summer evening Burt has an idea—but will Rachel accept the idea? If she does, will the idea add new excitement to their marriage, or destroy it?
