Vincent, co-founder of a software start-up, has been living in Paris for twenty years with Louise, his American wife, who has just launched a website to rent luxury apartments. But the cutting-edge software developed by Vincent is hacked by the competition, and suspicion creeps in between him and Louise.
Vincent is unaware that Louise is also working for the CIA, which has been paying paying particular attention to Fayed, one of her new clients. But the JKL affair disrupts the plans of the American Secret Service, which do not want this publicity around Louise.
Vincent, who has decided to leave the marital home for a while, is no longer under the pressure of the investigators. But, he feels desperate, trapped in deception, unable to trust his wife nor his partner. Meanwhile, Louise becomes more and more involved in a CIA mission that she is unable to fully understand.
