Director-cinematographer Bing Liu's award-winning documentary follows his own long-time friends over a decade as they come of age in the declining Rust Belt town of Rockford, Illinois. Caught between tumultuous relationships with their own families and bleak future prospects, they religiously pursue skateboarding for an outlet and a sense of community. As they become young adults, their camaraderie is strained by the weight of an unexpected fatherhood, racial identity issues, and unresolved domestic trauma.
