The Cleaner Comes at Midnight

A man is barricaded inside of an apartment building.

Madness reigns in the streets below.

Something has turned the people of Philadelphia into mindless killers, maniacs whose laughter fill the streets and alleyways.

When all seems lost, a military helicopter passes overhead. From it, a voice gives a cryptic message:

"The cleaner comes at midnight".

Is salvation at hand, or is it a final warning?
