The episode unravels in the rock valley where Wonkru is grieving the many homicides of their people from the previous episode. While the healers attend to the wounded, Monty notifies Miller about their scarcity of food and water, and suggests that Wonkru should surrender to Eligius. However, many of them do not to desire to return to the gorge, as they fear that they would be walking into another massacre. Bellamy, Madi, Murphy, Emori, Octavia, and Echo return to the valley in the rover. As Madi exits the vehicle, Wonkru begins displaying their faith towards her, believing that she may save them from death. Octavia suddenly pulls out her sword and begins to approach Madi before many members of Wonkru shield her, but Madi allows her to pass. Octavia plunges her sword in the ground and bows down to Madi, displaying her allegiance, much to everyone's surprise.
The next morning, Bellamy, Indra, and Madi visit Gaia, who is recovering from her near-fatal gunshot wound. The three discuss potential plans most likely doomed to fail. Gaia asks Madi to visit the commanders in the Flame for help in finding a plan that may actually work. Through visions created by the commanders, Madi ultimately reaches a seemingly decent plan. Gaia then hands her Octavia's commander emblem, declaring her Heda.
On the Eligius ship, Shaw is being brutally tortured by McCreary, with Raven being forced to watch. A prisoner tells McCreary that Wonkru has begun marching on the outskirts and are heading towards the valley for war. Consequently, he decides to amp up the torture by attempting to tear off one of Shaw's legs with a large pair of metal jaws in hopes of getting Raven to fly the ship. Just as he is about to rip Shaw's leg off, Raven breaks and agrees to fly the ship out of fear.
Meanwhile, Clarke enters Diyoza's prison cell, handcuffs her, then moves her the flight deck, where she confronts McCreary. Clarke holds a gun up to Diyoza's belly, threatening to kill her and McCreary's unborn child if the ship goes airborne.
Bellamy, Murphy, Echo, and Emori head towards the valley in the rover before being stopped by a group of prisoners, who begin opening fire. During the battle, Murphy gets hit with two bullets, wounding him. The prisoners then proceed to bring out a very large cannon. Before they are able to fire, Bellamy shoots a bullet into the cannon's barrel, causing an immense explosion that takes out the gunmen.
In the distance, Wonkru notices the explosion, and Madi orders Wonkru to charge and storm the valley.
McCreary learns that Wonkru has begun marching on the valley. In fear of being defeated, he opens Diyoza's strategy journal, and discovers a series of launch codes for a missile named Damocles, which was supposed to be used for weaponizing the hythylodium to leverage Eligius's way to the ground in the first place. This would destroy the valley if it were to hit the ground. Aware of the catastrophic damage this would cause, Clarke offers to surrender, but McCreary says that if he isn't going to have control over the valley, then nobody will. He enters the final launch code, unleashing the missile from the Eligius mothership, aimed directly for Eden.
Fourteen minutes remain until imapct. Not knowing what to do to survive, McCreary demands Shaw to fly them to the mothership. Clarke demands Shaw to fly the ship up to space or else she will shock Raven to death with her collar. He refuses to do so, and Clarke electrocutes Raven, who quickly grabs onto McCreary's metal armor, causing him to fall onto the ground, seizing, while Shaw takes out the remaining men on the flight deck. Clarke then stomps McCreary, killing him.
Wonkru makes their way into the village, and forces the miners to drop their weapons immediately. Madi orders the clan to execute them all, but Bellamy convinces her to change her mind. Still reluctant, Madi states she believes they deserve death after invading her and Clarke's home where they lived for six years. Bellamy responds with, "We've been here before, Madi. We were the criminals. The 100. We landed in someone else's home, and we went to war. You can execute them because they're the enemy or you can break the cycle. You can be better than them. You can be better than us." Raven's voice appears on the village speakers, who tells everybody to get to the ship as quickly as possible for immediate evacuation.
Murphy begins to pass out in the forest with Monty and Emori by his side, who both refuse to leave him behind. Instead of allowing all three of them to die, Monty tosses Murphy over his shoulders and proceeds to carry him to the dropship alongside Emori.
Clarke waits on the entrance of the dropship, with nobody in sight until Madi and Wonkru run towards the dropship, followed by the Eligius prisoners. Clarke refuses to allow them to enter, but Madi says that they must save their lives then let them prove they deserve it. Indra then asks Clarke where her mother is. Realizing her mother is not with the others, Clarke begins to run towards the village to find her mother before being stopped by Echo, who says they had a group go door-to-door who will eventually find and bring her.
Abby, who is frantically tending Marcus's wounds left by Vinson in the previous episode, is found by Octavia. She confronts her about her abandonment of Wonkru, before telling her they need to evacuate. But Abby refuses to leave Kane for dead. Octavia says she doesn't have a choice, but Abby still refuses. Octavia comes up with an idea to save all three of their lives.
With three minutes remaining until impact, Madi tells Bellamy he must forgive Clarke, after noticing their tension. In hopes of reestablishing their connection, Madi lets him know about how Clarke called him on a radio everyday for six years and seven days. Before being able to reply, Octavia, Abby, and an unconscious Kane arrive at the ship. With the missile now visible in the sky, Raven tells Clarke and Bellamy they have to close the door, but Bellamy says he will not leave Murphy, Monty, and Emori behind like he did with Clarke six years ago. With less than a minute until impact, the trio arrive at the door, finally allowing Clarke to pull the lever, closing the door. Before it closes, she catches a glimpse of the missile's impact that progressively consumes Eden in the blast. Raven and Shaw quickly ascend into the air, narrowly escaping the mass explosion.
In space on the Mothership, Bellamy finds Clarke in one of the cooridors. She delivers him good news about Murphy and Gaia's recoveries, but says that Kane was put into a drug-induced coma to help him somewhat heal, but it won't last long as his injuries are likely fatal. Bellamy brings up the idea of cryosleep, which would help keep Kane alive while they try to come up with an idea of saving him.
Diyoza spots Octavia sitting silently in the cooridor and joins her. She tells her that both of their biggest mistakes were their hunger for power - the "kiss of death." Octavia replies with, "One garden, two serpents. Eden never stood a chance."
Clarke and Spacekru later discuss how the fate of the human race are now in their hands. Shaw says that it will be at least ten years until the valley regrows, and that algae will only last a few weeks, meaning that cryosleep is the only option. The decision is up to Madi, who agrees with Shaw.
Clarke prepares Madi for cryosleep, and tells her how proud she is of her, before sealing her in the tube.
Then, Bellamy prepares Octavia for cryosleep. She mentions how their current situation parallels with closing the door in the bunker on the Ark, and tells Bellamy that she loves him. Bellamy says a part of him will always love her and the other wishes a part of her was dead, before putting her to rest.
Clarke and Bellamy awaken from their pods but question why they are the only people awake on the ship. Suddenly, a young man in his late twenties tells him that "that's the way [his] mom and dad wanted it." He introduces himself as Jordan Green, the son of Monty and Harper, much to the shock of Clarke and Bellamy. He tells the two that he has a message to play for them. Obviously confused, Clarke asks Jordan how long they were asleep. He responds with, "125 years."
Jordan plays Clarke and Bellamy a series of messages. The first one takes place approximately a year after everybody else went to sleep. Monty says that he and Harper decided to stay awake to monitor Eden's vegetation re-growth using geological equipment on the ship. The next video takes place two years after the cryosleep nap began, revealing Harper to be pregnant. They chose the child's name to be Jordan, named after Jasper. The third video shows Monty excitedly holding Jordan as a baby on his birthday. The fourth video takes place on the ten-year anniversary of the nap, the day everyone was supposed to be awoken, though Clarke and Bellamy are not yet woken up because nothing has grown on the Earth. The fifth video shows Harper and Monty at old age with tearful eyes after putting Jordan into cryosleep. Assuming that Clarke and Bellamy are watching the video in the future, Monty tells the two that Earth isn't coming back and is "as dead as they day [they] left." Before ending the video, Harper asks the two that to take care of Jordan. The sixth and final video takes place of February 8, 2206. A depressed Monty says that Harper has died after being stricken with a fatal genetic condition. After, he says they sometimes wished they had joined the others in cryosleep, but if they were to do so, they wouldn't be able to crack the Eligius III mission file. Monty reveals that after thirty years, he finally cracked it - it wasn't a mining mission, but instead a way of looking for another planet to tap for oil. Jordan uncovers a window, revealing a beautiful large Earth-like planet with two suns. Monty says he set the coordinates two weeks before the video was taken, and says they should arrive there in seventy-five years. He said he would have loved to put himself in cryosleep to see it, but couldn't do it without Harper. Monty ends the final video, saying "May we meet again." Clarke and Bellamy repeat the same words, hold each other, and look at their new home, hoping that things will be better there.
