Somewhere in Southern California, in a drug raid run by the US government, a beachfront property was seized and turned into a residence for undercover cops. They are all top agents of the DEA, FBI, and Customs and they are living in this house unofficially known as "Graceland". "Graceland" is a place full of secrets, and bad, good, and blurred moments too. The only idyllic thing is its outside look, but the lives of its residents are nothing like it. The lies which are in the base of their undercover work, are formed a web of lies that pervades everything. Coming of a new graduating at the top of his class, FBI rookie, Mike Warren (Aaron Tveit), could make the life of a legendary FBI agent Paul Briggs (Daniel Sunjata) and the others, more complicated or it could reveal the truth. It is based upon actual events. The agents struggle in the aftermath of the gang war while Briggs tracks down a loose end in order to bring Ari Adamian to justice. The feud between the Sarkissians and a local gang heats up; Briggs' motives are revealed; and Mike hunts for the sarin gas. Johnny goes undercover to stop a gang war; Jakes and Charlie set out to take over Germaine's business; and Mike begins to piece together Briggs' plan. Ari rises through the ranks of the Armenian mob; Briggs dodges new suspicions from his housemates; and Charlie and Jakes are one step closer to taking down Germaine. While Mike questions Briggs' true motivations in the Sarkissian Case, Charlie devises a new angle to catch Germaine.
