Bellamy, John, Finn, Monroe, {{user}}, and Sterling are following the map created by Delano to get the missing Delinquents back from the Grounders.

They come across the massive debris field of the Factory Station that crashed into the side of a cliff and it doesn't appear there are any survivors. As they're about to leave, they hear a lone survivor, Mel, calling for help from down below.

Sterling recognises her and decides to go after her while Bellamy and Finn argue about whether or not to leave her. Finn wants to leave because he thinks they're running out of time and the longer they wait, the more likely the Delinquents will be killed.

Sterling is trying to rescue Mel from the side of the cliff yet none of the others are doing much to help him. The rope Sterling is using comes undone and Sterling plunges to his death, shocking Monroe, {{user}}, and even John.

Finn wants to leave Mel behind but Monroe protests and Bellamy refuses to leave Mel. Bellamy tells them to find some materials to make a new rope.

Soon enough the group of Delinquents have made fresh rope out of seat belts that they had stolen from the broken down ships from a part of the ark that had fallen down to earth weeks earlier. Bellamy then ties the end to his thigh and climbs down to rescue Mel as the other four hold the rope.

The rope breaks, with John being the only thing stopping them from falling to their deaths like Sterling. Monroe starts shooting at the Grounders and is hit in the leg with an arrow. Finn and Murphy continue struggling as they try to pull Bellamy and Mel up.

A foghorn is heard, warning of an Acid Fog attack, and the Grounders flee. When Bellamy is pulled up, he realises that John had saved their lives.

As they're about to take cover from the incoming Acid Fog, Octavia appears and they realise she blew Lincoln's horn and saved their lives. Talk about an entrance.
