After 35 years in the United States, Donal (Alan Cumming) returns to his family-owned whisky distillery in the Scottish Highlands. When he left, his dear mother had died and, on the very day of her funeral, he and his brother Sandy (Brian Cox) wound up in a violent exchange with their father. All those years away provided Donal with the chance to become the version of himself that his chaotic family would never allow, but the wounds from that terrible time have never fully healed. Now, with the survival of their treasured family business on the line, Donal hopes to make amends with Sandy — and to find some desperately needed inner peace — before it’s too late.
