Wonder Woman is an American television series based on the DC Comics comic book superheroine of the same name. Starring Lynda Carter as Wonder Woman/Diana Prince and Lyle Waggoner as Steve Trevor Sr. & Jr., the show originally aired from 1975 to 1979.
In early 1942, during the Second World War, American pilot Major Steve Trevor (Lyle Waggoner) bails out during an air battle over the Bermuda Triangle, location of Paradise Island. The island is home to the Amazons: beautiful, ageless women with great strength, agility, and intelligence. Amazon princess Diana (Lynda Carter) rescues the handsome Trevor and helps nurse him back to health. Her mother, the Amazon queen (Cloris Leachman; succeeded by Carolyn Jones and Beatrice Straight in later episodes), decrees that Olympic-style games shall be held to select one Amazon to return Trevor back to America, but she forbids her daughter Diana, the princess, to participate. Diana states that since she is not allowed to participate, she does not want to be present for the games and will take a retreat to the other side of the island. The games are held with participants wearing masks and numbers (shown as Roman numerals in triangles on white sleeveless short tunic-dresses). Among the contestants is a blonde Amazon. During the events, the blonde Amazon shows exceptional skills and she ties for first with another Amazon. To break the deadlock, the "bullets and bracelets" event is decided as the tiebreaker, wherein each of the women takes turns shooting at the other; the one being shot at must deflect the bullets with her bulletproof bracelets. The blond woman wins the event, superficially injuring her opponent's arm. When she is pronounced the winner, she removes her mask and wig and reveals that she is Diana. Her mother, though initially shocked, relents and allows her to go to America.
Diana's costume, designed by Queen Hippolyta, features emblems of America, the land in which she will be returning Steve Trevor. A golden belt will be the source of her strength and power while away from Paradise Island. She has her bullet-deflecting bracelets and also receives a golden lasso which is unbreakable and forces people to obey and tell the truth when bound with it. As shown later in flashback, Hippolyta also teaches Diana how to transform magically into the costume.Diana, as Wonder Woman, flies to Washington, D.C. in an invisible plane. After dropping Trevor off at a hospital, the heroine stumbles upon a bank robbery, which she stops. A theatrical agent who sees her in action offers to help make her bullets and bracelets act a stage attraction. Diana is hesitant, but needing money in this new society, she agrees.
Meanwhile, Trevor's civilian secretary Marcia (Stella Stevens) is a double agent for the Nazi Fifth Columnists. She seeks to aid top spies in killing Trevor and opposing this new threat, Wonder Woman. Her first attempt is arranging for an accomplice to fire a machine gun at Wonder Woman during her stage act. Later, as spy activities increase, Trevor leaves the hospital but gets in a fight and is captured, prompting his "nurse" Diana to come to his rescue. Wonder Woman defeats Marcia in an extended fight sequence in the War Department. Having defeated Marcia, Wonder Woman thwarts a Nazi pilot who had plans to bomb the Brooklyn Navy Yard by using her invisible plane, and she rescues Trevor. With Marcia and the spy ring defeated, the film closes as Trevor and Brigadier General Blankenship talk about Trevor's new secretary whom Blankenship selected not only for her outstanding clerical test scores, but her decidedly plain appearance in contrast to Marcia: the bespectacled Yeoman First Class Diana Prince USNR(WR), Wonder Woman in disguise.
