I watched trailers for this film a few times before its release, and I was up for a movie with the actress from Hanna, Brooklyn, and Lady Bird; I recognised it was a film about alcohol addiction, so it is possibly one that could be nominated during Awards Season. Basically, the story is told in a non-linear order. Rona (Saoirse Ronan) is a young Irish woman recently out of rehabilitation following a decade of alcoholism treatment. Wanting to help clear her mind and remain sober, she returns to the family home on the Orkney Islands in Scotland. Her English parents, Andrew (Stephen Dillane), who is bipolar, and Annie (Saskia Reeves), who is religious, have been separated for a long time. Staying with them alternately, Rona helps her father on his farm and meets her mother's religious friends. Flashbacks show Rona during her student years in London, where she was a biology graduate. She often went clubbing and had a relationship with her boyfriend Daynin (Paapa Essiedu). However, Rona's drinking turns to alcoholism, causing problems in her relationship, and unintentional injury. Eventually, Daynin cannot cope with her behaviour and leaves her. One night, Rona is attacked while drunk. Soon afterwards, she enters rehab and completes a 90-day sober program. Back on the Orkneys, Rona struggles to connect with others. Rona decides to return to London, but on the ferry, she has an overwhelming urge to drink and abandons her plan to leave. She finds work with the Royal Society for the Protection of Birds which involves a systematic search for the rare bird the corn crake, listening for its distinctive call. One day, visiting her father, Rona finds him in a non-responsive state. On the side she finds his abandoned wineglass and dips her finger in the red wine to taste, leading to a brief relapse. Soon afterwards, Rona gets a job with the RSPB on the remote Papa Westray island, home to a tiny community. Living by herself, she connects with some of the other islanders and attends Alcoholics Anonymous. She still struggles to avoid the temptation to drink and tries swimming in the cold water. A fellow alcoholic who runs the grocery store assures her that he has been sober for several years and that it does become easier. During a windy winter on Papa Westray, she develops an interest in seaweed biology and her mother is pleased she is becoming healthier. As she prepares to depart that spring, Rona hears the call of a corn crake for the first time and laughs in delight. Also starring Lauren Lyle as Julie, Naomi Wirthner as Amanda, EastEnders' Nabil Elouahabi as Samir, Tony Hamilton-Croft as Gary, Conrad Williamson as Jack, and Seamus Dillane as James the Barman. Ronan gives a terrific raw performance as the girl trying to control her demons and her tempestuous nature. It is a simple enough story of addiction, although the backwards and forwards storytelling can be slightly confusing at times. However, it is good not to slip into drastic melodrama, the emotional moments are controlled and realistic, and the sights of the island (apparently this is the first major film set in the Orkneys) make for great viewing, a worthwhile drama. Good!
