FBI Special Agent Aaron Pearce, tall, muscular, a lone wolf with an attitude, is assigned to protect Mark Beecher, a witness to the plans for a terrorist attack. The discovery of an unknown informant within the FBI's ranks, however, forces the two men to hole up in a loft apartment with only one another for company.
After long conversations and their shared attempt to unravel the puzzle of the terrorist group's next target, Pearce and Mark find they cannot deny their mutual attraction. Pearce gives in to his passion, sleeping with the man he's sworn to protect and going against his training as he risks heartbreak once again.
When the informant reveals himself to Pearce and takes him hostage, Mark finds he cannot run and leave Pearce to die. Instead, their roles have been reversed and now he is the only person who can save Special Agent Pearce.
FBI Special Agent Aaron Pearce is recovering from his injuries suffered while on assignment in Detroit, stuck in the offices of the FBI running database searches for agents in the field. He is bored and edgy, and takes it out on those closest to him, including his live-in lover Mark Beecher.
While Mark cannot deny the heat between them, he struggles to find his place in Washington, DC, and in Pearce's apartment. He notices a car following him back and forth to work and panics, certain it's the terrorist mole Robert Morgan who escaped them in Detroit.
As Mark and Pearce try to identify the driver, Pearce is drawn into an investigation concerning the disappearance of data discs from government employees. He doesn't think twice about disobeying orders to stay out of the field, and risks not only his career, but his life as well, to join Mark in an undercover operation that will change their lives forever.
