The daring experimenter Dr. John C. Lilly dedicated his life to radical self-investigation and unlocking the mysteries of consciousness and communication. "My body is my laboratory" was the motto, and his research on the language of dolphins and whales -- as well as psychedelics and sensory deprivation -- assured his own cult status in 20th-century pop culture as the basis for Ken Russel's Altered States and Mike Nichols's The Day of the Dolphin. Directors Michael Almareyda and Courtney Stephens, along with narrator Chloë Sevigny, explore the life of a determined scientist and his experiments into the psychonautical unknown.
