In order to enter the village, first you must complete the test. Talk to Swanson in the entrance and if you're not sure what to answer, keep selecting alternately the "up" and "down" dialogue options. The first option you must select is "up".
Inside the village, you will meet Honest Dan near the tree. He isn't part of the community and he will ask you to help him find a caravan. If you have Charisma, you can convince him to pay you 50 bottlecaps in advance.
(Optional) Search destroyed caravan for clues
This additional objective isn't groundbreaking. You will see a marking that will lead you outside the city, near a broken caravan. You will be looking for lemonade, hidden in the blue fridge near the dead man.
Search Covenant for clues
The key information related to the investigation can be found in Jacob's computer (high security level). If you can't hack it, you must find the password.
The password is lying written on a note in the closed house near the gate. If you can't open the lock in the door (medium level), you must steal the key from any citizen by using the pickpocket skill. Once you obtain the proof from the computer, you can accept a bribe from Jacob and receive 100 bottlecaps. Optionally, you can also talk to Dan - this will provide his help later in the quest.
Alternative solution: If you have around 5 Charisma points, you can try to get some information from Penny the merchant. Ask her about the lost caravan, then gossip about Dan - an option requiring Charisma will appear. This option will allow you to obtain the evidence immediately and get to the next point.
Go to the lake on the west. There are door in one of the pipes - it's the entrance to the sewers. Inside you will face large numbers of weak human enemies and few turrets. The doctor will have a key to open the closed doors leading to the further part of the complex. After a while, you will reach a large room - look left and take the fusion core.
You will have to face a key choice in this quest after you reach a small prison with not-unfriendly doctor Roslyn Chambers. You can spare the girl or kill her. If Dan is with you, then after deciding to kill her you will have to fight him as well. There are three possible outcomes available...
Kill Amelia - a contract with doctor Roslyn
If you decide to fight Dan by accepting Roslyn's offer, Amelia - the captive girl - will be killed after the battle. You will receive 300 bottlecaps. You will keep the access to the village and you will be able to trade.
Free Amelia (while Dan is with you)
Use the terminal under the stairs to free the girl. Then, talk to Dan. You will receive reward and the quest will end. By default you will receive 300 bottlecaps, but by using Charisma you can increase the reward by 60, 60 and finally 120, which in total can give you 540 bottlecaps. However, you will no longer be able to return to the village - you will become the enemy of all the citizens.
Free Amelia (without Dan)
If you will go to the complex alone or you will kill Dan but free Amelia, you will be able to collect the reward for freeing her on your own. You must find her father, he is residing in Bunker Hill. You will be an enemy of the village and you will not be able to return there. From her father - The Old Man Stockton - you will receive 300 bottlecaps.
Quest rewards: experience, 300 bottlecaps (Dan can pay you more if you convince him with Charisma).
