Probably Needs A Better Title.

You have You Cant Go Home Again. You have Stranger In A Familiar Land. And you have this.

Basically, this is when a character who wants to escape some nastiness, or probably he just defeated the nastiness, and return home finally returns... and sees that his home is no different from the place he came from. 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 Lets 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.

Examples:

• Lord Of The Rings, the Scouring of the Shire.
• Doom 2 begins with this.
• Shin Megami Tensei: Devil Survivor has this as one of the multiple endings.

Needs more examples.
