In this melodrama, a loyal research psychologist escapes from Budapest after the nature of his work is discovered. He resettles in Scotland and soon resumes his work. His benefactors provide him a female assistant, and at first the stubborn scientist is not pleased. Eventually the two fall in love. Not long after the research is finished, they marry and for a time the two are happy. But then a terrible fire erupts and the assistant/wife dies trying to protect the researcher's valuable notes. The distraught doctor dedicates the rest of his work to her memory and then heads to China to work as a medical missionary.
