Iris Nixon is a passionate puzzle lover. By day, she leads an unremarkable life as a moderator tracking malicious content on social media, but by night, she shines on secret internet forums, solving the most complex puzzles. Her life changes dramatically when she receives a tempting offer to crack a secret code. Becoming the first to solve it, Iris finds herself in Florence, where she meets businessman Cameron Beck. She realizes that she has discovered a dangerously powerful technology and, realizing that the decryption could fall into the wrong hands, the girl decides to take a desperate step - she steals the code and hides in Sardinia. Pretending to be someone else, Iris uses all her skill and charm to remain unrecognized as rumors about her whereabouts spread wider and wider.
