A young woman is strangled to death while she is having an online chat with Adam Ross. The victim is 20-year-old Sass Dumonde, a French music student, who is actually studying in New York City. At the crime scene, the team finds that the murderer took one of her laptops, which belonged to Draga Financial, an investment firm under investigation by the FBI. Hawkes determines the face behind the mask of the killer is an employee of the firm. When Mac arrives at his office he finds him gone and targeting Adam. When the murderer tries to kill Adam, Adam is able to subdue him while the police arrive. In the end, Mac, having learned Adam previously hacked into Draga's system against his permission, puts him on a three-day suspension.
