Rescue from Paradise

 is a Fallout 3 quest. It is also an Xbox 360 and PC achievement.

To go through the Little Lamplight cavern, you have to speak with Mayor MacCready and agree to complete the quest Rescue from Paradise that he assigns you. Two residents of the town, Sammy and Squirrel, have been kidnapped by slavers from Paradise Falls, and MacCready demands their return. When you arrive at Paradise Falls, a man asks you to capture slavers and gives you a mesmerizer tool. When you get inside Paradise Falls you have to go to the slave cage at the back of the area and talk to the kids through the wire grate. They tell you that in order to rescue them, you must open the gate. To do this you can either tamper with a computer or rewire a junction box. Once the kids have escaped, Sammy tells you to meet him South-West of here. Speak to them again and they say that they are returning to Lamplight Cavern. You can now enter the children's town!

Alternatively if your speech skill is high enough you can bypass this quest entirely by convincing Mayor MacCready that you're OK by speech or having the Child At Heart perk.
