Seductress Leila Templeton flirts with Harleth Crossey at his wife Marcia's dinner party. After the intoxicated Harleth takes a midnight drive with Leila, his next-day apologies fail to assuage Marcia's humiliation. Later, Harleth's secretary calls Marcia to say that he will not be home for dinner. When the maid warns Marcia that the chauffeur is crazily threatening to shoot her unless she marries him, Marcia tries to contact Harleth, but is told by a lying switchboard operator that he is with Leila. Harleth's subsequent tirade expressing a need for "personal liberty" drives Marcia to seek a divorce. Two years later, Harleth marries Leila. After she responds to his complaints about her flirting by asserting her "personal liberty," Otis Vale, whom Leila has driven nearly insane with her teasing, abducts her. His frenzied condition causes their automobile to tumble over a cliff, killing them both. When Harleth learns that "Mrs. Crossey" has died, he imagines it to be Marcia, and rushes to her. The relief he shows convinces her that their "invisible bond" is intact, and they reconcile.
