An alien poses as a singer to record hypnotic records that will entrance humanity as to be helpless before an invasion force. His manager discovers him and concocts a plan to discredit the singer by asking his wife to pose as an abandoned woman with children that the singer has callously walked out on. She tells this story to the national media and the singer is shown the door of the recording studio. His plans for invasion foiled, he leaves Earth.
