Like Sunday, Like Rain (2014)

In Manhattan, 12-year-old Reggie is a gifted cello prodigy with abundant resources but a deeply solitary life. Eleanor, a 23-year-old sometime musician, is estranged from her family, out of work, dealing with boyfriend problems, and in need of both a job and a place to live. When she becomes Reggie’s guardian for the summer, two lonely lives are brought into an unexpected arrangement.
