This quest takes place in a vault. Starting from the top/first floor, there is a mole rat broodmother with two mole rats in the right room. On the second level, in the rightmost room, are three radroaches. On the same floor in the leftmost room are five radroaches. The third floor down is divided in two, the right side currently inaccessible from the left elevator. The left room from where you enter has three radroaches, and the room to the right of that has another three. When you head down a floor, the fourth floor is divided in three. Only the center room accessible, and it contains three mole rats. The fifth floor contains four mole rats in the leftmost room. Like one of the previous floors, it is divided in two. The left elevator can be taken back up to the left side of the fourth floor. It can also be taken to the bottom floor. The leftmost room you immediately enter in has a single alpha deathclaw. This deathclaw deals large amounts of damage to a single dweller, and can kill them quickly if they are not at full health. Once it is defeated, the room contains a legendary junk. The next room to the right contains a lunchbox, and a Mr. Handy box. The elevator to the right grants access to the previously inaccessible right sides of the third, fourth, and fifth floor. The right side of fifth floor has five radroaches. The right side of the fourth floor is clear of enemies, and the right side of the third floor has four mole rats.
