The true story behind the family drama “Rose-mead” may not be the saddest tale ever brought to the screen. But, boy, it’s up there.

Inspired by a shattering 2017 Times article by then-staff writer Frank Shyong (and now the first narrative feature film from LA Times Studios), “Rosemead” has long been a passion project for its star, Lucy Liu, also a producer. It’s not hard to see why.

This powerful account of humble, terminally ill Taiwanese American widow Irene Chao (based on real-life Rosemead resident Lai Hang), who takes the fate of her schizophrenic teen son into her own hands, offers the transformational role of a lifetime for Liu. Best known for stylish, commanding turns in the “Charlie’s Angels” and “Kill Bill” movies and in TV series such as “Ally McBeal” and “Elementary,” she’s a revelation here.

But the narrative also shines a crucial spotlight on L.A.’s Asian American community and its sometimes insular approach to handling emotional trauma, particularly mental illness. Shame over the condition’s perceived stigma, language barriers and a general fear of expressing oneself add to this cultural dilemma, one that hasn’t been widely explored on the big screen.
