New mother Beth takes a much-needed escape trip to Croatia, organized by her newly divorced best friend Kate. During a heartfelt dinner, Beth opens up about feeling stuck in her marriage with her husband Rob, sensing a bleak monotony in their relationship. As the night unfolds, they indulge in clubbing, where Kate whimsically suggests that Beth consider a one-night stand to spark some excitement in her life.
However, the following morning dawns with confusion for Beth, as she wakes up with a haze of forgotten details and discovers that Kate has vanished. Disturbed, Beth approaches Sebastian, the owner of their Airbnb, who ominously informs her that there will be additional charges for the two men they entertained during their night out. In her desperate state, she attempts to reach out to Rob and Kate's ex, Jay, but her pleas are brushed aside, given Kate's notoriously carefree nature. Turning to the police proves futile as well, with their indifference aggravating her anxiety.
Only Zain, a compassionate Syrian taxi driver who had consistently driven them during their escapades, takes her concerns seriously. With Zain's assistance, Beth uncovers Kate’s purse and phone, discovering that the men they met at the club were actually conmen posing as escorts. They had drugged and robbed both Beth and Kate during their time together, shaking Beth to her core.
Determined, Beth returns to the police, who finally initiate an investigation into Kate's disappearance. In a harrowing turn of events, Beth becomes a suspect herself as evidence surfaces of drugs and potential sexual assault in her system. As she navigates the swirling emotions of betrayal and panic, she tries to uncover the dissonance between her memories and the available evidence, all whilst reaching out to Jay, who reveals his awareness of the affair between Rob and Kate, deepening her sense of betrayal.
Confrontation with Zain intensifies her suspicions about Rob's potential involvement, culminating in a direct confrontation with him about the affair. Yet, the police's growing allegations against her connected to Zain, who has dubious ties to a human-trafficking ring, deepen her despair. Zain maintains his innocence regarding the murder while asserting that he had no agency over his circumstances since he was smuggled into the country.
Amid the chaos, Beth takes matters into her own hands, discovering that the Airbnb host, Sebastian, has been secretly recording their actions. The chilling footage she uncovers reveals both her compromised state from that night and Kate being confronted and robbed by the escorts, followed by her indecipherable fate. Just as Beth makes vital notes from the recordings, Sebastian catches her in the act, prompting a struggle that ends in her escape.
With Zain by her side, they pursue the last trace of Kate's night, leading them to critical witnesses and ultimately unveiling a complicity made up of deceit and corruption among the very authorities she sought help from. As they dig deeper, Beth learns that Pavic, a cop, played a crucial role in concealing the truth about Kate’s disappearance.
In a climactic series of confrontations and revelations, culminating in Pavic's demise, Beth discovers the chilling truth about Kate's death and finds a way to clear her name, as well as unraveling the web of lies spun around her by her husband Rob. It is revealed that Rob's desperation to keep their affair from being exposed led to a deadly confrontation with Kate.
Realizing the true purpose of Kate's invitation to Croatia was to remind her of her own worth, Beth resolves to reclaim her life and protect her daughter from the toxic ties that have ensnared her. As justice takes its course, Beth prepares to leave her turbulent past behind, finally ready to embrace a future filled with promise, knowing that she is a survivor.
