As the fear of communism was rising in the U.S. after World War II, government officials set their sights on developing a weapon that sounds straight out of science fiction: mind control. This effort was led by the CIA in a program called MK-ULTRA, which was made up of 149 "subprojects" involving more than 80 academic institutions, prisons, and organizations. In this episode, we learn the dark history of MK-ULTRA and examine the origins of Subproject 68: Dr. Ewen Cameron's experimentation on patients at the Allan Memorial Institute in Montreal.
