We open with a two teenagers at a local drive-in making out and out of nowhere shots ring out killing the male teenager in the car. Stillman introduces Rush to FBI Agent Diane Yates, a personal friend and colleague of his, who needs our teams help in investigating a recent murder case of Mel Shaver who was shot dead while walking his dog. Yates, a no nonsense aggressive agent shares nothing with our team in terms of why the FBI wants in on this case. Yates does tell Rush that she's the reason Stillman's marriage ended. Ballistics reveal that Shaver was killed by a serial killer who stopped killing for 27 years but has come out of retirement. In order to find a connection between all our victims, our team breaks down all their backgrounds and whereabouts which eventually lead us to Bill Shepard, a ex-marine who once owned a local drive-in which was taken away by the bank. We track down Bill Shepard's son, Paul, who claims to have not seen his father in thirty years. They track down a PO box where Bill's been receiving VA checks and are about to interview the postal clerk when suddenly shots fly out of no where killing our clerk. While frantically trying to end our killer's rampage our investigation is stalled when it's revealed that Yates wasn't cleared to work this case. However, Rush finds a way to gets Yates out of debriefing and they track down Bill's cabin only to discover that he's been dead in the basement for years. The serial killer is still out there.
