Jay and Tyler head to Deer Harbor, Maine, Will's hometown. The FBI discovers new evidence regarding the museum bombing. Meanwhile, Jay and Tyler talk to a woman who had planned to leave her hometown with Will after the bombing.

Jay and Tyler's search leads them to Boston where a security box is uncovered containing aliases Will used and evidence about the bombing. After being captured by his bosses, Will Traveler undergoes interrogation and reveals what happened on the day of the Drexler bombing. A key arrest made by the FBI shows that the Drexler conspiracy goes far beyond what they had initially imagined.

Tyler and Jay risk a return to New York in order to investigate possible financial ties to the bombing. While Will Traveler seeks to avenge his girlfriend's death and bring down the organization, the FBI discovers that one of their own might be involved in the conspiracy.

For the first time since the bombing Jay and Kim reunite. Meanwhile, Will is searching for Maya's killer in New York. After discovering FBI ties to the bombing Tyler must stop Jay and Kim from taking evidence to Agent Marlow.
