The Mary Boyle documentary will have its first American screening in Washington DC this week.
It will be shown by the Solas Nua Centre in DC, an Irish cultural centre in the city.
Film-maker and journalist Gemma O’Doherty will give a talk about the case afterwards.
It is the first of several American screenings, with the next taking place in New York early in the year.
The documentary, ‘Mary Boyle: The Untold Story’ has been viewed by almost a quarter of a million people, with the bulk of views coming from the US.
