Cordelia is struggling to live with an incident which happened in her past and is currently living with her twin sister Caroline in a flat in London. When she gets involved with Frank and upstairs neighbour everything would quickly begin to unravel.
From the start we are not fully sure what to expect next from Cordelia, as the confusion between her dreams and reality are put across to the viewer. Her nightmare about the tube and the links to the 7/7 bombings quickly become clear, as a survivor of this attack. As this is referenced and would make perfect sense for her now fear of the underground tube system.
Something very interesting about this film as that by the poster and then the look of the flat it appears as a period drama, but that is certainly not the case as everything is then set in present day. The dark and dingy appearance links to her mood and general state of mind. This is a very big part of the film and clicks into a psychological thriller genre, which has you doubting pretty much everything.
When Cordelia meets Frank everything seems way too good to be true and her state of mind will again doubt him. Leading to some rather disturbing moments which I did not see coming at all. That would be a very good approach when it comes to this film, expect the unexpected. I definitely reached a point where I had no idea what was going to happen next and that is a positive when it comes to a film in the thriller/horror type genres. Its certainly a mixture of those two with drama as well, quite difficult to just nail down one in my opinion given the sudden changes not only between scenes but within them as well.
Antonia Campbell-Hughes is utterly outstanding in the leading role of Cordelia and also doubles up as her twin Caroline. It is not an easy performance and she must put in many different emotions and the sanity of her character is not straightforward at all. I am very interested to see which roles she will get after this leading performance. Johnny Flynn works very well with Campbell-Hughes and they both really do drive the film together and this is impressive.
