So at some point in Agent 98-27-3901's life, he got on the wrong side of Better Living Industries' city mandates. He did something terrible, perhaps treasonous, and they magnanimously allowed him another shot at life. They wiped his memories, gave him a gun, and sent him out to do some good with the blank slate they allotted him. Regular meetings with a psychiatrist are meant to ensure that he won't relapse, and that he only recalls certain memories under controlled circumstances - because some of those memories might be of use to his employers.

The problem is, it's been four years now, and he doesn't think he's getting any better. That's fine, though. Things could be worse. All he has to do is keep his head down and he can carve out a tolerable existence for himself.

How hard could that be?
