On April 13, 1953, CIA director Allen Dulles authorized Project MKULTRA, the controversial series of experiments aimed at developing mind control techniques and discovering a "truth drug."

Agents dosed subjects with LSD and other psychotropic narcotics, hypnotized them, and exposed them to radiation and electroshock therapy. Some of the participants volunteered, but others did so unwillingly and unwittingly.

The CIA attempted to destroy all records of the program, leaving behind only seven boxes of official files overlooked during the document purge. But a few stories survived. One of the strangest revolves around a series of uncontrolled experiments named Operation Midnight Climax.
