I love a zombie movie, Richard! This sounds a bit like a combo tagline+logline to me. With a logline, you want to think of it as a two sentence-long synopsis of what your piece is ultimately about (tall order, I know) & keep it absolutely clear, concise and compelling.

A helpful formula with framing your logline is "protagonist+inciting incident+obstacle+stakes". So, for example:

"An NYPD officer tries to save his wife and several others taken hostage by German terrorists during a Christmas party at the Nakatomi Plaza in Los Angeles."

I hope that this is helpful!

I know what that movie is, Angela Cristantello. :)

Another reason not to write the same, everyone can copy you.
