Sofia McKendrick (Natalie Dormer) is a blind pianist living at an apartment in London, traumatized by her family’s murder by Serbian paramilitaries. Her neighbour, Veronique (Emily Ratajkowski) is the daughter of Serbian philanthropist Zoran Radic (Jan Bijvoet), a war criminal of the Bosnian War, suspected of running criminal organizations. Despite this, Sofia seemingly had an amicable relationship with Veronique. During a discussion in an elevator, Veronique discreetly slips Sofia a USB drive and tells her that the perfume is "Liquid Gold". Later, Sofia witnesses Veronique fall to her death after a struggle in her room. However Sofia denies witnessing anything to the police Detective Mills (Neil Maskell), while hiding the USB drive.

Sofia performs at an event hosted by Radic, overhearing Radic and his associates discussing the circumstances of Veronique's death; with Radic to be the one behind it. There, Radic's head of security Alexandra Gordon (Joely Richardson) and her brother Marc (Ed Skrein) have a discreet conversation revealing Veronique was pregnant and that Marc was sent to kill her; Marc had an affair with her and is likely the father of her child. Radic becomes fixated on Sofia for her connection to Veronique, and Sofia ends up having to dodge police questions and Radic's men looking over Veronique's apartment.

After Marc rescues Sofia from an attempted assault and kidnapping, Sofia bonds and starts an affair with him, learning that Veronique committed suicide out of paranoia. It’s revealed Sofia has her own vendetta towards Radic, conspiring with her adopted father Niall (James Cosmo), a soldier who rescued her as a child. Sofia hands Nial the drive, with “Liquid Gold” being the password, uncovering Radic's assets and operations. Sofia recounts her sister, Balma, who could see but pretended to be blind for Sofia’s benefit; Sofia's family were friends with Radic in Bosnia, but Radic betrayed them, leading the paramilitaries in their massacre. Veronique planned to expose her father's crimes, and gave Sofia the drive to do so.

Sofia learns that Alexandra is seeking the drive, hoping to use it to usurp Radic’s operations. Sofia hands Alexandra a copy in exchange for a photo with Sofia in (identifying her) and a private audience with Radic at Veronique's funeral. Sofia threatnes releasing the usb information if Alexandra shows anyone the photo. Alexandra gives Radic a copy of the photo at the funeral. Sofia confronts Radic, who realizes the truth of Sofia's past. Radic claims he was in love with Sofia's mother, and raped her before she became pregnant to a blind daughter, and believes Sofia is his biological daughter. Radic leaves, as Sofia is left emotionally devastated. Detective Mills looks into Sofia's past, discovering that "Sofia" is an alias, named after Niall's biological daughter who died in infancy. Niall himself soon passes away in the hospital.

Radic discovers Alexandra's treachery, ordering her death; despite the appeal from his sister, Marc abandons Alexandra for her involvement with his unborn child's death. Radic arrives at Sofia's apartment to personally kill her, while Marc rushes to her rescue. Meanwhile, Mills watches surveillance of Sofia's visit earlier in the front office, noticing she's looking at something. Mills realizes she analyzed Marc's wanted poster and makes his way to her apartment. As a fight ensues, Marc takes out Radic's men, while Radic overpowers and prepares to kill Sofia, as Sofia attempts to stab him. Marc arrives and shoves Radic out the window, impaling on a spiked fence.

As Sofia looks over Marc, there is a final revelation; she was never blind, and is in fact Balma. During the massacre of their family, the real Sofia was killed while hiding. Balma was rescued, taking Sofia’s identity, feigning blindness for years. Because of this, she previously saw a Wanted Poster and realizes that Marc is a wanted fugitive. Marc encourages her to run, while he takes the fall for Radic's death, and Sofia flees the apartment before the police arrive.

The film, which features Dormer nude and contains a sex scene, has been criticised for what some critics called "gratuitous nudity".^[10][11] Dormer dismissed this in an interview with The Guardian, saying, "There has to be sexuality in the power play of a thriller. We have all got bodies, after all. In this film the sex scene, which for me was a love-making scene, is a metaphor for the way my character connects with the part played by Ed Skrein. Nakedness is a good equaliser and the shower scene also shows the tattoos on my character's body and makes it clear she is not quite who you think."^[12]
