Diana was born on the paradise island of Themyscira, where the Greek goddess Hera sent her mother Hippolyta and the remaining Amazons to where they would be protected from the ravages of time and be able to rebuild their community after a bloody battle waged against them by Ares the god of war. Hippolyta created the form of a baby girl out of clay and raised it up to the sky. The gods answered by giving the clay form life and flesh, and she became Hippolyta's daughter Diana. Among her elder sisters, Diana reached maturity and the stature of her fellow Amazons, becoming a more proficient fighter than Artemis.
Years later American military pilot Steve Trevor crash-landed on the island when it mysteriously appeared out of nowhere, having escaped a dogfight where he lost two of his fellow pilots to unfriendly aircraft. Diana chased after Steve, and though he was not hurt, he was captured and interrogated by the Amazons for anything he knew about the island. Realizing that he was no threat, Hippolyta decided that one of them should safely escort him back to his homeland, with a contest to be held among the Amazons to determine who should be worthy of that task. Diana wanted to be the one who will escort Steve Trevor back to America, but Hippolyta forbade her from doing so, feeling it's her duty as a mother to protect her daughter from the dangers of the outside world. Instead, Diana was sent for guard duty at the prison where Ares was being held.
Alexa, one of the Amazon sisters who preferred a good book over fighting, came to take Diana's place at guard duty while she participated in the contest wearing a helmet to mask her identity. During the contest where Diana had beaten all her opponents, even in the final one where two contestants were to deflect arrows shot at them wearing silver bracelets, Persephone killed Alexa and let loose Ares from his prison. After Hippolyta awarded Diana, the winner of the contest, with the armaments and uniform she would wear as their representative to the outer world, the Amazons discovered that Persephone betrayed them. Now Diana must also find and stop Ares.
Flying Steve back to America with an invisible jet, Diana was astounded by the sight of children playing in the park, though she was also offended by its society's treatment of women, accusing it of brainwashing females to believe they are weak and helpless while having them trade off on their feminine charms to attract males. Despite her attitude, Steve helped Diana track down Ares by using the military computers to report sudden acts of violence within the area of Greece. Soon she confronted Deimos, who had been sent by Ares to take her down and bring her remains to him. She ultimately defeated him, but before she could extract any information from him with her magic lasso, Deimos turned to ashes, leaving behind his helmet and a medallion that Diana recognized as that of Tartarus, the underworld.
Diana and Steve travelled to Greece, where they find a militant stronghold comprised of members of the Cult of Ares. It is at this particular location where Ares was about to make a blood sacrifice that would open the doors to Tartarus in the hopes that its ruler Hades would break the iron bands that keep Ares from his godly power. Diana and Steve attempted to stop the sacrifice from taking place, but Ares summoned a couple of winged creatures to keep the two intruders at bay. Diana told Steve to stop Ares, but when Diana was overpowered by one of the winged creatures, Steve chose to save Diana instead, bringing her to a nearby hospital where she recovered, though now angry that Steve chose to save her. Steve told Diana that he believes the world isn't worth saving if she isn't part of it. Meanwhile, in the chambers of Tartarus, Ares convinced Hades enough to break the iron bands, enabling him to use his powers at its fullest once again.
Diana and Steve then travelled to Washington, D.C., where Ares summoned his demonic hordes at the Lincoln Memorial to wage war with all mankind, hopelessly overmatched until they saw the Amazons arrive on shore in boats and winged horses. While Steve took off in the invisible jet to deal with destroying the missile that the President of the United States had launched before it reached Themyscira, the Amazons dealt with Ares' army of undead Amazons fighting under his control -- which included Alexa, who clued her sister Artemis with a mystic chant that would break Ares' control over the undead Amazons. Diana in the meantime fought Ares by herself, who by now had the power to command lightning to strike his adversary. Drawing him to the Reflecting Pool of the Lincoln Memorial, Diana lassoed Ares and had one of his lightning bolts strike him instead, stunning him long enough for her to behead him. With Ares now rejoined with his son in Tartarus and no longer in control, his demonic hordes vanished, the Amazons returned to Themyscira, and Diana and Steve reunited at the Reflecting Pool after he came home succeeding in destroying the missile.
Back on the island, as Artemis tried to take up the hobby of her deceased sister Alexa, both she and Hippolyta saw Diana sitting alone, pining to see Steve again. Hippolyta believed it was time to reopen channels of communication between their worlds and had Diana become their ambassador to the outside world, allowing her to fulfill her wish only on the grounds that she would visit home often. Diana eagerly accepted.
In America, Diana was slowly getting used to her civilian identity and allowing herself to enjoy her femininity when she and Steve noticed a scuffle going on between the police and a humanoid creature called the Cheetah. Diana scurried into action, transforming into the uniform of a superheroine that a little girl she befriended in the park calls "Wonder Woman".
