Plot
On the day S.H.I.E.L.D. fell, S.H.I.E.L.D. engineer Alphonso "Mack" Mackenzie is saved from Hydra double agents by agents Bobbi Morse and Isabelle Hartley, who have infiltrated the devastated S.H.I.E.L.D. aircraft carrier Iliad on former director Nick Fury's orders to save the commanding officer, Robert Gonzales, and to sink the ship and its sensitive cargo and give S.H.I.E.L.D. at large a chance to survive against Hydra. They find Gonzales with a severely wounded leg, and struggle to assist him. Morse plans for Hartley to clear the way for Mack to get Gonzales to safety, while she sinks the ship, but when Hartley finds other S.H.I.E.L.D. agents fighting back against Hydra, she and Mack convince Morse and Gonzales to help them rather than kill them by sinking the ship, going against Fury's orders. This was the beginning of their own faction of S.H.I.E.L.D., one that is against Fury and his secrets.

In the present day, Morse steals the "toolbox" that Fury gave new director Phil Coulson, but is confronted by Melinda May, while Coulson confronts Mack about his allegiances. Morse and May fight, but when reinforcements arrive to help May, Morse overrides the bases systems, creating an opportunity for herself and Mack to escape capture. At "The Retreat", a safe house for people with abilities that Bruce Banner created for himself, Agent Skye tries on the gloves that Agent Jemma Simmons created for her, intended to inhibit her new-found earthquake abilities. Though they assist with dampening the vibrations, they cause light headedness in Skye. She is visited by Gordon, a teleporting man with no eyes who explains how her gift can be used for good, tapping into the vibrations of all things. He offers to take her to a safe place where people like them can help her master these powers, and leaves her to make her own decision.

Simmons manages to detain Morse when the latter underestimates her, but when May finds a gas mask in Morse's possession, they realize that Morse and Mack never intended to escape. Dendrotoxin gas fills the base, knocking all those inside, bar May, unconscious. The agents of "the real S.H.I.E.L.D." that Morse and Mack work for enter the base and take control. Agent Tomas Calderon learns of Skye's whereabouts and asks to lead a team to detain her. Morse decides to go with him. At the cabin, Skye removes the gloves and successfully manipulates the movements of water, realizing that Gordon was right. Soon after, May calls her to warn of the incoming danger.

Gonzales explains to Coulson that they want his help in opening the toolbox, to ensure that none of Fury's secrets can harm S.H.I.E.L.D. or the rest of the world again. Coulson refuses to help, and May arrives, knocking Gonzales out and helping Coulson escape, before surrendering to Agent Anne Weaver. Skye runs from the S.H.I.E.L.D. agents hunting her, who Morse has ordered to use knock out bullets rather than real ones, as Skye is a S.H.I.E.L.D. agent just like them. Calderon, who has had bad experiences with gifted individuals before, tries to shoot Skye with a real gun, and as she attempts to defend herself, her abilities bring down a large section of the surrounding forest. A branch hits Calderon in the chest and Skye, horrified at what she can do, calls to Gordon for help. He promptly appears, and takes her away.

In an end tag, Coulson meets up with Lance Hunter, who agrees to become a permanent S.H.I.E.L.D. agent, and the two begin planning their next move.

Marketing
For the final twelve episodes of the season Marvel once again ran the "Art of..." initiative, in which an image was released the Thursday before the episode aired, depicting a first look at a key event from the upcoming episode, with the season's title being "The Art of Evolution". The different artists were once again chosen to create the teaser posters, based on their previous work and how it connected to the themes and emotion of the intended episode. "One Door Closes", an episode focused on Bobbi Morse's history, received a poster of her with the "real S.H.I.E.L.D." logo, that "embraced the basics" of four-color printing, utilizing magenta, cyan, black and yellow, while still having layers and complications, much like the character of Morse. The poster was designed by Delicious Design League, who executive producer Jeffrey Bell explained were chosen because "We try to come up with what would be a good fit based on the artist. And what I like about this image, and what I like about them in general, is if you look at their work ... from a distance, it's a simple, clean graphic. It's visually striking. And you get close, and there's just a ton of stuff going on. There's just lots of detail, lots of little things, lots of movement, and I do love that ... in printing, these are process colors: magenta, cyan, black and yellow. Those are the basics of all four-color printing. And the fact they sort of embraced the basics like that, kept the basics there and then threw overlaying and complications and made it so much more than that, I think also speaks to the character".

Home media
The episode began streaming on Netflix on June 11, 2015, and was released along with the rest of the second season on September 18, 2015, on Blu-ray and DVD.
