| The Real Inspiration Behind That Night: Are Elena, Paula and Cris True Story Characters? (Credits: Netflix) |
Netflix’s Spanish psychological drama That Night (originally titled Esa Noche) centres on a chilling family dilemma: how far someone might go to protect their own blood. The story follows three sisters — Elena, Paula, and Cris — whose holiday in the Dominican Republic spirals into chaos after a fatal car accident leads to a desperate decision that binds them together in secrecy. The show unfolds as a tense examination of loyalty, guilt, and the consequences that follow when one impulsive moment changes everything.
The central question viewers keep asking is whether the troubled Arbizu sisters are based on real people. While the series feels strikingly realistic, the truth behind the characters reveals a different origin — one rooted in fiction rather than real-life crime.
The characters of Elena, Paula, and Cris are not based on real individuals. Instead, the trio originates from the 2021 mystery thriller novel That Night written by Gillian McAllister.
The Netflix adaptation reshapes the story for television but keeps the novel’s core moral dilemma intact: what would you do if someone you loved asked you to help hide a terrible mistake?
In the original book, the protagonists are siblings named Joe, Cathy Plant, and Frannie, and the story takes place in England with the accident unfolding during a trip to Italy.
For the Netflix series, creator Jason George relocated the narrative and renamed the characters, transforming them into the Arbizu sisters while preserving the emotional core of the story.
Despite the geographical and character changes, the DNA of McAllister’s novel remains visible throughout the show. The narrative still revolves around a catastrophic accident, a secret shared between siblings, and the long emotional fallout that follows when they return to their everyday lives.
McAllister herself has spoken about the theme that drives the story: the complicated line between love and moral responsibility. The author described the story as a question about how far someone would go for their sibling — whether loyalty might push someone to lie, break the law, or even help hide a body. That dilemma forms the emotional backbone of the Netflix series.

Why the Story Feels So Real
Although the Arbizu sisters are fictional, their dynamics are written in a way that mirrors real-life psychological patterns. The show portrays Elena, Paula, and Cris as deeply connected, almost inseparable, with a level of loyalty that borders on self-destructive.
Their willingness to cover up a crime for one another is portrayed as the result of a shared childhood trauma. That past binds them together in a way that shapes every decision they make as adults.
This approach reflects a concept often discussed in psychology: trauma bonds between siblings. When children experience hardship together, their relationships can develop into intensely protective connections. In some cases, those bonds can produce strong loyalty, while in others they may create unhealthy patterns of dependency.
By grounding the story in these psychological realities, That Night manages to feel believable even though the characters themselves are entirely fictional.
The Series Uses Fiction to Explore Real Moral Questions
Stories about siblings committing crimes together do exist in real life, but That Night does not directly draw from any specific case. Instead, the show uses fiction to explore the emotional and ethical weight of family loyalty.
Through Elena, Paula, and Cris, the series examines how guilt spreads through a family unit and how secrets reshape relationships over time. Each sister processes the aftermath differently, forcing them to confront the question of whether protecting family can come at too high a cost.
That emotional complexity is what gives the series its psychological edge. Rather than focusing purely on the crime itself, the show spends more time examining how people rationalise difficult choices when loyalty and morality collide.
Viewer reactions to the Arbizu sisters have been sharply mixed since the series debuted on Netflix. Some fans sympathise with Elena, seeing her as a frightened mother whose panic sets the story in motion. Others argue that Paula and Cris should never have agreed to help hide the accident, calling the decision reckless and morally questionable.
Across fan discussions, one theme appears repeatedly: the uneasy feeling that the sisters’ choices feel disturbingly plausible. Many viewers say the drama’s biggest strength lies in forcing audiences to imagine what they would do in the same situation.
Other netizens have praised the performances of the cast, noting that the actors portraying the three sisters capture the tension and emotional complexity of their bond. The show’s quiet, character-driven storytelling has also sparked debate about whether the sisters are victims of circumstance or architects of their own downfall.
Fictional Characters With Real Emotional Weight
In the end, Elena, Paula, and Cris are not based on real people. Their story comes directly from Gillian McAllister’s novel, reimagined for the screen by Jason George and Netflix’s Spanish production team.
Yet the emotional realism of the characters — shaped by trauma, loyalty, and moral conflict — is what makes That Night resonate with viewers. The show may be fictional, but the questions it raises about family, guilt, and responsibility feel uncomfortably real.
Did the Arbizu sisters make the only choice they felt they had, or did they cross a line that can never be undone?
