From the comic's purchase page:

“Overwatch is overrun. The terrorist organization, Talon, is unleashing famished creatures of unknown origin in droves to demolish and devour our heroes. At this point, it’d take a miracle to save them. Sadly, Mercy is all out of miracles, and may not even have the power to save herself from the jaws of the Hunter Gamma…”
