بعد يومين من المذبحة التي وقعت في قرية لينكولن ، كان كلارك وبيلامي جالسين في الخارج في منطقة البار في كامب جاها . إنهم يراجعون خريطة كلارك للأنفاق عبر Mount Weather ويناقشون خطة عمل لإخراج الجانحين . فين و ميرفي النهج وكلارك يعترف أنها لم تحدث على الفنلندي لأنها حصلت على العودة. يغادر بيلامي للحصول على المشروبات ويسأل فين عن خطة ماونت ويثر. أخبر مورفي كلارك أنه تم تبرئتهم لأن العفو الذي تلقاه الجانحون لإرسالهم إلى الأرض يتضمن وقتهم على الأرض. لا يزال كلارك لا يتحدث مع الفنلندي حتى يغادر الفنلندي.وصلت Raven وأخبرت مورفي أن تغادر قبل أن تكشف لكلارك أنها اكتشفت سبب عدم سماعهم لأي من المحطات الأخرى : لقد قام Mount Weather بتشويش إشاراتهم. شاهد الرائد بيرن المحادثة وأخبر آبي عن التطور الجديد. في وقت لاحق ، بينما يشرح Raven لكلارك كيف قام Mount Weather بالتشويش على إشاراتهم وحتى تحطمت Exodus Drophip التي سقطت في يوم الوحدةيقاطعهم "آبي" ويحاول إيقافهم. يقنع كلارك ورافين آبي بضرورة إنزال برج الراديو في Mount Weather حتى يتمكنوا من العثور على أي ناجين آخرين من Ark للمساعدة في بناء جيشهم. تطلب آبي من بيرن البقاء في الخلف وحراسة المعسكر لأن آبي ستذهب معهم إلى ماونت ويذر.

في هذه الأثناء ، في Mount Weather ، تحاول الدكتورة Lorelei Tsing إقناع Dante Wallace بالسماح لها بمواصلة التجارب على الـ 47 الجانحين. يرفض دانتي ويخبر كيج والاس أنه إذا أصدر الأمر بحصاد الأطفال ، فلن يستحق رؤية الأرض مرة أخرى. يغادر قائلاً إنه سيجد متطوعين بدلاً من ذلك. يخطط كيج والدكتور تسينج أنه في حالة عدم وجود متطوعين ، فسيتم المضي قدمًا على أي حال.

يقوم كلارك وآبي ورافين والعديد من سكاي بيبس بالتنزه سيرًا على الأقدام إلى ماونت ويذر لإخراج برج الراديو. يناقش كلارك وآبي موقف فين وكيف أبرأه المجلس.

كين و Jaha على حد سواء المحاصرين في Grounder السجن. جاها يخبر كين أن وقتهم لم يحن بعد لأنه لا يزال لديهم عمل يقومون به. يدخل غوستس مع بعض المحاربين ويبدؤون بضرب جحا. يخبرهم كين أنهم جاؤوا بسلام. يخبرهم غوستس عن مذبحة توندك ويقول إن "الدم يجب أن يكون دماً". يترك وراءه خنجرًا ويخبرهم أن أحدهم سيموت بيد الآخر وعندها فقط سيسمع شروط استسلامهم. يترك وراءه فتاة ، ليكسا ، للتأكد من إتمام الفعل. تخبرهم ليكسا أنهم إذا رفضوا القيام بذلك ، فسيستخدم القائد السكين لقطع حلقهم.

As Jasper is released from Medical, Dante approaches him and explains to him about the radiation problems the Mountain Men deal with and how their current methods pale in comparison to the Delinquents' blood. He asks Jasper to try to get his fellow Delinquents to volunteer to help out the Mount Weather residents.

Clarke, Abby, and Raven have stopped to survey Mount Weather and look for the radio tower. Abby realizes that Bellamy and Octavia have taken off on their own to find another way into Mount Weather. She sends Sgt. Scott and two other Ark Guards off to go find them. Finn volunteers to go after them, too, but Clarke stops him. Finn gets upset because of the way everyone is acting toward him since the massacre and storms off with Clarke following after. Acid Fog suddenly starts rolling toward them and Clarke and Finn take off for the bunker.

Bellamy and Octavia are looking for another way into the mountain when Sgt. Scott stops them and tells them to come back. Critters start scurrying across their feet and Bellamy realizes that the Acid Fog is coming. Octavia follows the bugs and discovers a hidden door leading to an underground parking garage. Bellamy and Octavia rescue Sgt. Scott and one of the Ark Guards but the other guard is swallowed up by the fog.

When Clarke and Finn get to the bunker, Clarke sees Delano's corpse still sitting there. Finn covers it up.

Abby and Raven have taken cover in a tent from the Acid Fog as Raven attempts to get a signal. She picks up an encrypted channel and realizes they will be able to listen in on Mount Weather.

In the parking garage, Sgt. Scott gives Bellamy a gun and he and the other guard split up from Bellamy and Octavia.

Clarke and Finn discuss the awkwardness between them and Finn gives Clarke back her father's watch that had been around the dead Delano's neck.

Jasper is trying to convince the other Delinquents to volunteer to give blood but no one wants to. Monty tells Jasper that he is going after Clarke just as Maya enters. She starts talking to them about "pizza day" while holding up a pad of paper saying that "they're listening" and to follow her. She takes Monty and Jasper to a storage room where it is private and explains to them that she found out the breach was not an accident. She then reveals to them the Harvest Chamber and that she is scared they are going to be next. She explains to them that without the treatments, everyone would die. Monty wants to try getting out like Clarke did, but Maya says it will not be possible now since security has been increased. Jasper says that for now, they need to buy some time by volunteering.

While they are still trapped by the Acid Fog, Raven breaks the encryption on the radio channel and they overhear the Mountain Men discussing "the veil". Abby tells Sgt. Porter to get ready to blow the radio tower to find out if there are any other Ark survivors, but Raven tells her if she does blow the tower, then they will not be able to listen to the enemy anymore and that she knows what Clarke would do.

Sgt. Scott and the other guard are looking around the parking garage and into cars. Sgt. Scott finds a wind-up toy that plays Christmas music. They are suddenly attacked by Reapers. Bellamy and Octavia hear the screams and go to investigate where they find two Reapers eating the Ark Guard. Bellamy shoots them both before they find a third Reaper hovering over Sgt. Scott's body. Octavia recognizes it as Lincoln and calls out to him but Lincoln attacks her. She shoots him in the leg and Bellamy knocks him out and they flee.

Kane and Jaha discuss the difference between murder and sacrifice as they decide whether to follow Gustus' orders or not. Kane picks up the dagger and offers it to Jaha, telling Jaha to kill him; however, Jaha refuses. Kane then cuts his own wrist and Jaha begs Lexa to help him. Lexa tosses him a bandage before Jaha takes her as a hostage.

Bellamy and Octavia are hiding in the back of an abandoned car, discussing what they're going to do with Lincoln. Bellamy promises Octavia that they will get Lincoln back.

Gustus and the guards enter where Jaha is holding Lexa hostage. Lexa then takes out Jaha and holds the knife against his throat before revealing that she is, in fact, the Commander. She says that Jaha will be used to send a message and they drag Jaha away because "the massacre must be answered".

Octavia calls Lincoln to her and Bellamy uses the Ark Guard's shock baton to knock Lincoln out. He then tells Octavia that they're taking him home.

As the Acid Fog lifts, Clarke tells Finn that she doesn't know who he is anymore and he says that he does not either.

Back at Mount Weather, several of the Delinquents are "volunteering" for harvesting. Dante tells Dr. Tsing and Cage that all they had to do was ask. Dr. Tsing leaves and Dante grabs hold of Cage, telling him that he knows about the breach and if he finds out Cage had anything to do with it, then Cage would never assume the presidency after Dante.

The Delinquents are recovering in their dorm as they discuss waiting on Clarke to break them out of Mount Weather.

مرة واحدة كلارك وآبي يلتقي احتياطي في كامب Jaha، آبي يقول كلارك أن قرروا ضد تهب برج الراديو لأنهم ليس متأكدا مما اذا كان هناك أي ناجين سفينة لكنهم هم على يقين من أن هناك 47 سكاي الناس المحاصرين في جبل الطقس. عندها فقط يقترب جحا ويقول لهم أن لديه رسالة من القائد: "ارحلوا أو متوا. لدينا يومان".
