Earth One is supposed to strip away the decades of embellishment and give us a more down-to-earth, naturalistic take on the character, is that right? Okay.
Set it in 1942. Real world war, real Air Force, real Nazis.
Diana and Steve return from Paradise Island to find that Pearl Harbor has taken place. President Roosevelt decides to keep the existence of the Amazons temporarily a cabinet secret. He sets up a false American identity for her, as Diana Prince, USAF intelligence analyst, with Trevor as her control.
Diana just adores American culture, though she's puzzled at the maze of double standards among men and women. She also has a rather summary hands-on way with injustice. "Who is this Wonder Woman?" the papers are asking, the third time she foils a mob shootout. (No costume yet.)
Something big is brewing on the war front. V-2 rockets are only part of it. Diana and Steve have to go undercover. There is a capable fifth-column operation keeping the Axis plan secret, headed by one Paula von Gunther.
Suborned by von Gunther, some sexist opinionated poobah has Diana dismissed from intelligence, and assigned to babysit a class of female war orphans, on the premises of dilapidated old Holliday College.
Amazon training time!
You will believe a man can fly.
You will believe a man can dress up like a bat and fight crime.
And you will believe a woman can revive the morale of several dozen traumatized teenagers.
And prep some of them to infiltrate a murderous fifth-column group.
And turn some of them into aircraft maintenance engineers, in no time flat.
And instruct some in weapons, pilotry, parachuting and hand-to-hand combat.
And at the same time expose the Axis master-plan, which is nothing less than an airborne invasion of the USA, to take out industrial facilities, dockyards and munitions plants, plus Princeton and Los Alamos.
Unbelievable? The Nazis think so. They're not ready for anything like this.
But Diana Prince is Wonder Woman!
