Day of the Dead 2: Contagium

In 1968, an infected man from Russia, Rubinsky, is being operated on at a military hospital when soldiers arrive and begin to shoot all of those who are in the building. One of the hospital students steals a strange vial, enclosing it in his thermos. He is later shot by the soldiers as he attempts to escape through the woods and the thermos is dropped. The soldiers in the hospital continue to kill any one that has been in contact with the infected man. The zombies are killed when C4 is detonated by sharpshooters outside the hospital.
