The film, described as an “emotional detective story,” unfolds at the start of World War II. It centers on 9-year-old violin prodigy Dovidl, a recent Polish-Jewish refugee to London. His brother Martin, of the same age, is devoted to him.
Hours before Dovidl’s debut concert performance at the age of 21 he vanishes without a trace. Decades later, a young violinist shows Martin, now in his late 50s, a stylistic flourish that could only have been taught by Dovidl. This prompts Martin to begin a search overseas for his lost brother, “one that will lead to surprising revelations for both men and for Helen, the woman who stood between them.”
