Blue Raven Ridge is a United States Air Force installation also employed by the United States government as a containment facility.
After the death of S.H.I.E.L.D. Director Jeffrey Mace and the assassination attempt of Glenn Talbot, S.H.I.E.L.D. was labeled defunct and investigated. The Armed Forces seized equipment from S.H.I.E.L.D., including Zephyr One, and stored them in the base. A group of soldiers led by Lieutenants Evans and Lucas track down agents and came to the Rae's Restaurant in order to arrest them. They only found Leo Fitz and captured him.
Fitz was taken to the Blue Raven Ridge and interrogated because he was suspected of having helped the other S.H.I.E.L.D. agents to escape. Fitz denied all the accusations but acknowledged that he was responsible for the death of Director Mace. He then offered to fully cooperate in order to locate the other S.H.I.E.L.D. agents, being provided books to elaborate on multiple theories. While looking for his friends, Fitz sent fan letters to a football magazine. However, over the course of six months, none of them proved to be relevant and General Hale grew wary of Fitz's failed attempts.
Former S.H.I.E.L.D. agent Lance Hunter began to receive coded messages from fan letters from Fitz. Hunter disguised himself as an attorney to break him out of his prison. As Fitz attempted to discuss his own personal escape plan spanning over a month, Hunter revealed that he came up with his own and intended to break him out right then. After blowing out the wall to the prison, Hunter and Fitz left the building to immediately see Rusty Peltzer accidentally kill himself by crashing the helicopter they were supposed to leave in. So, they instead got away in Rusty's RV.
Hunter and Fitz then worked together to break back into the facility, using false identities and ferrets as a distraction. They soon enough found the capsule, while also discovering the Zephyr One, which was also put into storage. After fighting their way through some soldiers, they escape with both the capsule and the Zephyr.
After they successfully stole equipment, Hale summoned Evans and Lucas. They feared that they would be downgraded because of their failures, but Hale simply executed both of them in cold blood.
