The team investigates a missing woman's boyfriend, with whom she lived. However, they determine that he has a twin brother and quickly turn their attention to him.

While searching for a Manhattan-based woman who disappears on the morning she was scheduled to leave town, the team soon becomes suspicious of her live-in boyfriend and his twin brother.

The team quickly suspects the missing Julie Cochran?s live-in boyfriend, Greg Knowles, when they discover that the town car that was scheduled to take Julie to the train station at 8:00 AM was canceled by a man that morning and the doorman never saw Julie leave the building. However, questions arise about Greg?s smug twin brother, Rick, with whom Julie appeared to be flirting at her going away party the night before. The team also finds it curious that Greg fails to mention the recent murder of a well-known homeless woman at the shelter where he, Rick and Julie volunteer -- whose prized necklace was found in the suitcase of Julie?s that turned up at the train station.
