The multinational consulting company Ji-mini is on the verge of commercializing a new type of connected glasses that record the wearer’s data, designed to act as a personal coach and suggest how to get the most out of his or her life. But a series of sabotage attacks damages the company’s underwater computer cables. Ji-mini appoints a private detective agency to find the culprit. To solve the case, Gary, one of the detectives, unofficially teams up with his childhood friend Jean Melville, a staunch defender of open source software, who is suspicious of Jimini's real intentions.
