“Hail Hydra” is the salute used by the fictional terrorist organization of the Marvel Universe named Hydra and the opening line of the group’s official motto, which reads: “Hail Hydra! Immortal Hydra! We shall never be destroyed! Cut off one limb and two more shall take its place! We serve the Supreme Hydra, as the world shall soon serve us!”
A undercover officer named Rogers is the only one who can get in close enough to the criminals that terrorize neighborhoods with drugs and violence. However, he finds himself becoming part of the problem as he almost becomes what he’s trying to bring down.
