Diana Prince (played by Lynda Carter) is captured bound and dragged hither and yon by two Chinese agents while trying to find the mountain fortress of a mad scientist with a beam weapon that can trigger volcanic eruptions. She escapes from her bonds and after an interlude as wonder woman she returns and fakes escaping so she can be captured by the mad scientist's right-hand man and taken back to his headquarters.
