American Falls (2013)

In a rural town in southern Idaho, a Japanese-American family owns and operates a small motel. The year is 1965, the height of the Civil Rights Era. One night, a stranger sporting 'city clothes' checks in, the first Black man that Toru Suzuki's children have ever seen. Yoshiko, Toru's precocious 13-year-old daughter, takes it upon herself to solve the mystery of this man, especially after two detectives come knocking on their door in the middle of the night.
