Sofia is a 25-year-old anthropology student from the UK who currently works in a London café. She has placed her doctoral studies on hold to serve as the primary caregiver for her chronically ill mother, Rose. She feels trapped in a state of personal stagnation and passivity. During her time in the coastal town of Almeria, she seeks to cultivate boldness, break her lifelong habits of accommodation, and explore her own desires.

Rose is Sofia's mother, a woman who suffers from a shifting array of undiagnosed illnesses, currently manifesting as lower-body paralysis. She raised Sofia alone in England after her Greek husband left the family. Rose uses her poor health and constant need for assistance to ensure Sofia remains tethered to her, operating from a deep-seated fear of abandonment.

Ingrid is a tall, physically imposing German seamstress spending the summer in Spain. She works remotely, repairing and embroidering garments for various clients. She projects intense confidence and freely explores her desires, though she masks deeper insecurities and complicated emotional boundaries regarding her past and her sexuality.

Dr. Gomez owns the medical clinic in Almeria where Rose seeks treatment. He employs highly unconventional diagnostic methods, frequently ignoring his patients' stated complaints to focus on their psychological states and relationship dynamics. He strongly opposes the overuse of medication and treats the family unit rather than just the individual.

Julieta is the resident physiotherapist at the Gomez Clinic and Dr. Gomez's daughter. Outside of her clinical duties, she is a painter who creates self-portraits. She quietly rebels against her father's strict anti-medication rules by drinking alcohol, feeling trapped in her role at his clinic much like Sofia feels trapped by Rose.

Christos is Sofia's 69-year-old father who abandoned his family in England when Sofia was five years old following a religious conversion. He now lives comfortably in Athens, owns a shipping company, and centers his life entirely on his faith and his new, younger family. He refuses to take responsibility for Sofia's struggles or Rose's care.

Alexandra is Christos's 29-year-old wife and a mainstream economist currently on leave from her job in Brussels. She is highly intelligent, fluent in multiple languages, and perfectly willing to play the role of a submissive, childlike spouse in exchange for the stability Christos provides. She evaluates relationships through a lens of strict self-interest.

Matthew is Ingrid's boyfriend who works as a life coach for corporate executives. He holds a deep disdain for Dr. Gomez, openly labeling him a fraud, and leverages his professional connections in the pharmaceutical industry against the clinic.

Juan is a student who works at the beachside injury hut in Almeria. He provides medical attention for swimmers stung by the local medusas and develops a casual sexual relationship with Sofia, offering her a space free from heavy emotional expectations.

Pablo is Sofia's neighbor in Almeria who runs a local diving school. He keeps a dog chained outside that barks incessantly, creating a constant source of background tension and frustration for the neighborhood.

Tony James is a pharmaceutical executive and one of Matthew's life-coaching clients. He aggressively opposes Dr. Gomez's medical practices, specifically his refusal to prescribe standard medications, and uses his influence to investigate the clinic.

Covarrubias is a health official from Barcelona who arrives at the clinic to review Rose's official complaint against Dr. Gomez. He evaluates the clinic's practices alongside the pharmaceutical executive.

Dan is Sofia's coworker from the café in London. While Sofia is away in Spain, he temporarily takes over her living space back home, slowly encroaching on her personal territory.

Leonardo is a riding instructor who works at the stables where Ingrid stays. He engages in flirtatious banter with Ingrid and treats Sofia with cool suspicion.

Evangeline is the infant daughter of Christos and Alexandra. She commands the full attention and resources of her parents, standing in sharp contrast to her older half-sister, Sofia.

Hannah is Ingrid's younger sister who lives in Dusseldorf. Her difficult childhood history and past physical trauma heavily inform Ingrid's current fears regarding closeness and responsibility.

George is a colleague of Christos's at the shipping company in Greece. He briefly interacts with Sofia, casting an appreciative eye on her revealing outfit.

Ingmar is a masseur living near Sofia in Almeria. He shares Sofia's intense irritation regarding Pablo's barking dog and occasionally interacts with her around the neighborhood.
