For 25-year-old Stephanie, life changes the day a compromising and humiliating video of her mother goes viral. Stephanie is convinced that the video, which destroyed her political career and undermined her powerful family clan, is a fake. And this despite the opinion of all the experts who certify its authenticity. But who could have forged it, and why? Stéphanie, who has no talent for lying and is neither a spy nor a policewoman, is hired under a false identity by a start-up company she suspects has the technological capacity to create undetectable hypertrucages. Drawn unwillingly into a dangerous plot with international ramifications, Stéphanie discovers that the truth is not where she expects it to be, and that perfect lies come at a high price.
