After Robert and Brill get captured by Reynolds' men, Robert tells Reynolds that the tape is at a restaurant nearby. They go inside, and it turns out Robert double-crossed them by leading them into a mob den. The mobsters have another tape, one that will incriminate them and they don't want to give it up. Reynold's tries to get the tape back, thinking it is the one that shows him killing the senator. The mobsters, Reynolds and his men end up all shooting each other dead while Robert hides under a table. Brill escapes. The FBI storm in and arrest everyone else. We see a short interrogation of two hackers who thought it was all a training mission. Then Robert back at his house sees Brill on his tv and knows he is being watched...
