Digging to China (1997)

"Two innocent outcasts. One incredible friendship."

Precocious young Harriet and her older sister Gwen live at their mother's motel in small-town New Hampshire. Harriet dreams of a life beyond her inattentive family and the stultifying town. A mentally disabled man named Ricky comes to stay at the motel, and Harriet finds him kinder and more interesting than anyone she has ever met. After tragedy strikes, Harriet and Ricky cling to each other ever more tightly.
