Winner of the Prix du Jury in Un Certain Regard at Cannes, Harmonium observes a family as it's dealt a tragic blow and then no less shaken by the process of recovery. Toshio (Kanji Furutachi) runs a garage workshop that opens right into the home he shares with his wife, Akié (Mariko Tsutsui), and their cute-as-a-button daughter, Hotaru (Momone Shinokawa). Trouble arrives when Toshio hires Yasaka (Tadanobu Asano), a friend with an unsavory past who's in need of a break—though the complicated effects of his arrival on the close-knit family are best left unrevealed.
