LILTING features intensely moving performances by Asian cinema's legend Cheng Pei Pei as Junn, an immigrant mother grieving the untimely death of her only son Kai (Andrew Leung), and Ben Whishaw as her son's lover, Richard. Jun's grieving is disrupted by Richard's visits and his attempts to communicate are first met with distrust. Richard hires Vann, a young translator, who helps piece together the tender memories of the man they both loved.
