The film opens with Angus Barrie, an Irish Republican Army member, walking through hills, and coming to rest on a beach, where there is a little hut. Meanwhile, Nancy Gulliver having just left school, burns all her books in happiness. It is her birthday, and her aunt has invited over Harry, with whom she’s desperately in love, to tea. However, during the course of the film, as a result of Harry’s behaviour with another girl and the way he treats Nancy, she realises that her love for Harry was nothing more than childish infatuation. One day, Nancy goes down to the beach, and notices that her hut has been slept in. She leaves a note requesting that it be left alone. Soon after, she is on the beach reading, when Barrie comes up to her. Over the course of the film, the two develop a relationship, despite her not really knowing and understanding his job: he is one of the first people that became part of a group named the IRA, and is on the run from the government. Nevertheless, she grows fond of Barrie, and dubs him "Cassius" After Cassius asks her to pass on a message to a colleague, several Officers of the British Army are gunned down at a horse race show. Later that day, Captain Rankin of the Black and Tans comes to see the Family, and asks if anyone knows where Cassius is. The officers' suspicion is aroused when Nancy's grandfather says he saw her talking to a man on the beach. She denies any knowledge. When they leave, she runs to the hut on the beach where Cassius was staying to tell him to flee, only to find that he has already packed. As they walk out, a light shines on them: the Black and Tans have found him. He is gunned down, much to Nancy's distress. The film ends with Nancy back at home, considerably older and wiser than when the film started.
The Dawning was filmed in Ireland in the mid-1980s, largely on location in Ireland.The beach scenes were filmed extensively at Goat Island, a small cove on the Irish coast, close to the county boundary between Cork and Waterford. Some "Big House" exteriors were shot at Woodbine Hill in the same district. Incidentally, it was Rebecca Pidgeon's first feature film, and Trevor Howard's final film; he died shortly after production ended, and the film was dedicated to him. It was also Jean Simmons' first feature film for nearly ten years. Despite having contributed largely to the production, Bernard MacLaverty was uncredited as a screenwriter. The film was shown at the AFI/Los Angeles International Film Festival, the Cannes Film Festival, and at the Montreal World Film Festival. Actors Anthony Hopkins and Hugh Grant reunited five years later in the Academy Award-nominated film The Remains of the Day.
Critical reception
The Dawning was received largely positively by the critics, with a five star review from Time Out, describing the film as "solidly crafted... its main strength lies in the performances" and mentioning that Rebecca Pidgeon had given a "remarkable debut". China Daily noted that Hopkins had played his character "wonderfully".
