“Crazy Rich Asians” breakout Awkwafina takes center stage in Lulu Wang’s “The Farewell.” A trailer just dropped for the critically acclaimed Sundance pic.

Based on an actual lie, the dramedy sees U.S. raised Billi (Awkwafina) returning to Changchun, China and being pressured to go along with a morally ambiguous ruse. Doctors have revealed that the family’s matriarch, Nai-Nai, has mere weeks to live. Everyone knows — except Nai-Nai herself, and the family intends to keep it that way. To ensure that her final days are happy ones, they celebrate an expedited wedding as an excuse to bring the family together.

Billi thinks Nai-Nai should know the truth, and questions whether it’s “wrong” to lie, and in doing so deny her the opportunity to say goodbye. Everyone else sees the lie as merciful — it’s too painful to deal with the truth, and Nai-Nai would be sad during her last weeks on earth.

“You think life belongs to oneself, but that’s the difference between the East and the West,” Billi is told. “In the East a person’s life is part of a whole: family.”

“The sublime is a short distance from the ridiculous, and this film allowed me to explore that distance,” Wang told us. “It’s also a very personal story that depicts the proximity of grief and joy, pathos and humor.” The writer-director explained that she’d like audiences to “feel more than think, and if they must think, then I want them to not know what to think. The movie raises a lot of questions that I intentionally left unanswered, because in life there’s never one simple answer,” she emphasized.

Wang made her feature debut with 2014’s “Posthumous.”

“The Farewell” lands in theaters July 12.
