Captain America; Bucky; Anzel (villain, introduction); a Japanese spy ring (villains, introductions)
A girl's dying brother creates a bioweapon which produces a localized death rain and leaves the formula in a locket he wishes buried with him because he thinks the weapon is too awful to use. He doesn't destroy it outright because he wants his sister to give it to the war dept. if things start looking really bad. Japanese hear of the weapon's one field test and wish to acquire it so they dress up as zombies while they search the cemetery for the brother's body. Cap and Bucky bust them up, and during the fighting the locket is dropped into a furnace and destroyed. Cap says that it is just as well because America would never be in such dire straits that it would use such a horrible weapon.
