Basically, this is when a character who wants to escape some nastiness, or probably he just defeated the nastiness, and finally returns home... and sees that the nastiness is there, too.
It can happen in the middle of the plot or be a finale. In case of the former, it can trigger Let's Get Dangerous! or give the unlucky homecomer a level in badass when he finally decides to give the nastiness a fight. In case of the latter, it can be a Shoot the Shaggy Dog ending.
