They are told that the outside world is infected by poisonous gas.It became unfit for human habitation, and the remaining survivors took refuge in the bunker and formulated rules to maintain the operation of the new society in the bunker.

A revolution broke out in Silo 17, and the residents inside the silo fled to the outside world.At this moment, Juliet stepped into the abandoned silo, and her footsteps shuttled among the bodies scattered outside the entrance.She explored upwards layer by layer and found that the upper floors were empty, while the lower floors were mercilessly swallowed by floods.Faced with the fact that the bridge leading to the IT department was in ruins, Juliet decided to build a temporary bridge on her own.However, when she carefully stepped on the fragile bridge, it collapsed under the weight.

Bernard was monitoring Juliet's every move through the suit camera on her body, and saw her approaching the No. 17 launch silo step by step. However, at this moment, the camera signal was suddenly interrupted.He knew in his heart that Juliet's refusal to carry out the cleaning task was undoubtedly a challenge to the existing ruling order. This act of resistance was likely to trigger a revolution.To stabilize the situation, Bernard acted quickly, placing deputies under Sims' command and imposing a mandatory curfew as a way to control the silo residents who were confused about Juliet's life or death.

Meanwhile, Bernard is trying to win over Meadows as he plans to deliver a speech and have Walker and his ex-wife Carla imprisoned for secretly handing over tapes recording the footage of Juliet's suit.Juliet.However, Shirley did not back down from these changes. She continued to stir up emotions at the bottom and demanded a clear answer.Upon seeing this, Knox quickly stepped forward to dissuade Shirley. He knew that the price of revolution was heavy, and hoped to try his best to avoid war and protect his people from harm.

Under the watchful eyes of everyone, Bernard gave a speech. He claimed that the IT department had produced a new tape that would allow Juliet's life to continue, but at the same time he insisted that Juliet was no longer alive.During his speech, Meadows expressed support for Bernard.While most Silo residents were receptive to this explanation, Shirley remained skeptical.

When Juliet learns of the existence of dozens of silos, she realizes that her actions could spark a revolution within the silos.Zoro tried to communicate with her, not only providing her with food, but also suggesting that she put on a fireman's uniform and leave quietly.At first, Solo was determined not to give up the vault, but at the moment Juliet was about to leave, he changed his mind.Seeing this, Juliet offers to help him get to the upper level.
