Digital Babylon - S1.E5

A serial killer is targetting girls who work in the internet sex industry. He is tracing the home addresses of those who strip in front of their own web cameras and then killing them why they are online. Sosh takes this personally and begins her own 'cyber' investigation, against Annies instructions, and takes more and more risks while doing so. Meanwhile the rest of the team are running down leads in the real world, trying to catch the killer before he strikes again.
