Vault 112 is located in the far west of the Capital Wasteland and is hidden underneath Smith Casey's Garage. It was built to suit the needs of Dr. Stanislaus Braun who created the Garden of Eden Creation Kit. There's a virtual reality simulator inside the vault, those who entered were promised to live a perfect life within the simulator.
However, the residents didn't know that they could not leave the simulator without Braun's permission and after so many years Braun got bored of the perfect life and began killing, then resetting them occupants. During the Tranquility Lane quest you can put an end to the their missery by executing the failsafe program within the simulator.
