A traumatized woman trying to recover gets super freaked out in her sister’s basement flat, maybe due to a creepy upstairs neighbor who plays the cello, or maybe just because her brain is making stuff up, leaving everyone confused.
🍿 Cordelia: Detailed Plot Synopsis
A Lingering Trauma
Cordelia, a young woman deeply affected by an unspecified past trauma, seeks refuge and stability. She moves into a London mansion flat alongside her twin sister, Caroline, and Caroline’s boyfriend, Matt. The flat, previously their late father’s, carries its own sense of history and atmosphere.

Alone in the Flat
When Caroline and Matt leave town for a weekend, Cordelia is left alone in the spacious, somewhat isolated apartment. This solitude amplifies her vulnerability and psychological state. She begins to interact with the charming yet increasingly strange young man living upstairs.

A Disturbing Neighbor
The upstairs neighbor, Frank, is a cellist whose music drifts down into Cordelia’s flat. A relationship develops between them, initially appearing as a potential connection. However, Frank’s behavior becomes unpredictable and disturbing, blurring the lines of trust and reality for Cordelia as her isolation and past issues intertwine with the present.

💥 Cordelia Reviews
Personal Review
Okay, so I went into ‘Cordelia’ expecting a straightforward thriller, but wow, it’s more of a psychological deep dive that messes with your head. I was genuinely creeped out by the atmosphere in that basement flat – it felt so isolated and eerie. Antonia Campbell-Hughes is absolutely captivating, she really sells the trauma and confusion. The scenes with Johnny Flynn as the cellist were so tense, you never knew if he was genuinely charming or totally sinister. That ambiguity really got under my skin, in a good way. I’ll admit, the ending left me feeling a bit lost. It doesn’t wrap everything up neatly, which is cool for some, but I wanted a *little* more clarity after all that build-up. Still, I couldn’t stop thinking about it for a while after, which says something about its impact.

Professional Reviews
- Film Insights Weekly: “Adrian Shergold’s ‘Cordelia’ crafts a potent, suffocating atmosphere, largely thanks to Antonia Campbell-Hughes’ committed performance. The film delves deep into psychological distress with claustrophobic intensity. While the mood is undeniable, the narrative becomes increasingly opaque, perhaps too much so for some, leaving the ending feeling less like an ambiguous puzzle and more like an unfinished thought.
Audience Reactions
The intensely creepy atmosphere and lead performance really stuck with people.: Many viewers praised Antonia Campbell-Hughes’ acting and the film’s success in creating a tense, psychological mood.
The ambiguous plot and ending sparked lots of debate and confusion.: A frequent topic was the film’s lack of clear answers, leaving audiences divided on whether it was artfully mysterious or just frustratingly vague.
Overall Consensus: A moody and well-acted psychological thriller praised for its atmosphere and lead performance, though its ambiguous plot and ending proved divisive for many viewers.

🤨 FAQ
The film ‘Cordelia’ is intentionally ambiguous about the specific nature of Cordelia’s past trauma. It is heavily implied to be a significant, disturbing event (some reviews suggest a connection to a real case like the 2007 London bombing, though the film doesn’t explicitly state this connection as definitive plot). The focus is on the psychological impact and her ongoing struggle to recover, rather than detailing the event itself.
The film plays with themes of psychological instability and perception. While Cordelia’s twin sister, Caroline, is introduced as real, the ambiguous nature of the plot, particularly in the later stages and the ending, leaves open the possibility that Caroline, or aspects of her presence, might be elements influenced by Cordelia’s psychological state or trauma. The film does not definitively confirm or deny her full reality.
Frank is the upstairs neighbor who is a cellist. He initially appears charming and forms a connection with Cordelia when she is alone. However, he becomes increasingly strange and disturbing. The film’s ambiguous ending casts doubt on his true identity and whether the interactions Cordelia has with him are entirely real or partly imagined due to her psychological condition.
The ending of ‘Cordelia’ is designed to be interpreted. The final twist, where Cordelia receives a call from Frank after seemingly confronting him, strongly suggests that the narrative is filtered through Cordelia’s unreliable perspective. It likely indicates that her experiences, particularly the disturbing interactions and climax, are manifestations of her trauma and psychological breakdown rather than purely external events. It leaves the viewer questioning what was real.
Yes, several critics and viewers have noted similarities between ‘Cordelia’ and Roman Polanski’s 1965 film ‘Repulsion’. Both films are psychological thrillers that focus on a young woman experiencing a breakdown while isolated in an apartment, where her deteriorating mental state leads to increasingly disturbing perceptions and events, blurring the line between reality and delusion.
Yes, the late actor Michael Gambon appears in ‘Cordelia’. Notably, it was his final film role before his death in 2023. However, his appearance is very brief, described by some viewers as more of a cameo.
