Watch FilmoFlix. ‘Blue Smoke’ follows a rest-home caretaker, Joe, who is mistaken by an elderly resident, Beryl, for her for her lounge-singing ex-husband. Joe plays his doppelgänger in the hopes of swindling her, until he realises she’s broke and dying. When she’s finally taken into palliative care, he finishes off the story of his doppelgänger’s departure to comfort Beryl, and sings her ‘their’ song: NZ classic, Blue Smoke.
