This Chinese film portrays an old woman’s heroic battle for a palsied young man’s soul.

Astute, articulate, ambitious 20-year-old Liu Chunhe (Jackson Yee) has struggled with cerebral palsy all his life. Superficially, it’s his mother, Chen Lu (Jiang Qinqin), who cares for him; in reality, it’s his maternal grandmother, Chen Suqun (Diana Lin), who does.
