Steve Rogers and Anthony Stark, better known as Captain America and Iron Man, get into a whirlwind romance during World War II. When Steve crashes his plane and wakes up in the 21st century, he thinks his whole world is gone. The Avengers become his family, though, and Iron Man is still a hero. Of course, after so many years, there's another man piloting the suit. Steve's lost Anthony forever.

Steve doesn't know the new Iron Man's identity, but he becomes good friends with him all the same. And then Iron Man is forced to reveal himself, and Steve learns the truth: that it's still Anthony, not aged a day, and perhaps more importantly, that Anthony is a vampire.
