Lord Falsworth has resumed his WWI role
as Union Jack in order to aid the Invaders (Captain America,
Bucky Barnes, Sub-Mariner, Human Torch, Toro) in their mission against the
Nazi vampire Baron Blood. The problem is, when his daughter
Jacqueline Falsworth sees this she flies into a rage, blaming Cap for luring her father into danger. She collapses in a faint and then they realize she has been bitten by a vampire—so Baron Blood must know His Lordship is Union Jack. Nephew John is unharmed (since he is Baron Blood in disguise)....
That night, the Invaders again patrol
the city, with Union Jack reluctantly staying home to watch
Jacqueline. As soon as the heroes have gone, John resumes his Baron
Blood guise and hypnotizes His Lordship into passivity while preying
again on Jacqueline. As they all must, Blood recounts his origin for
his intended victim: he is really Lord Falsworth's brother who, on a
visit to Transylvania, met and was vampirized by Count Dracula
himself; with the world on the brink of war, Drac dispatched John to
join the Germans and wreak havoc on his native Britain. As Blood
attacks, the Human Torch, having stayed behind to keep an eye on the
suspicious John, intervenes. Blood seizes Jacqui and flees with Torch
in pursuit—but the rain outside douses his flames and the baddie
kicks him in the head. He awakens only when Union Jack arrives,
having snapped out of his trance. Torch summons the other Invaders
while UJack traces Blood to a nearby cavern. The two enemies fight
and it ends with the vampire hurling a huge rock which crushes the
hero's legs. The others arrive and the Baron manages to keep them all
at bay, until Ujack manages to push the rock off his legs, rolling it down an incline and knocking Baron Blood back onto some pointy
stalagmites. As the villain dies, the others discover that Jacqueline
is dying and they need to get help immediately....
