A research scientist explores the boundaries and frontiers of consciousness. Using sensory deprivation and hallucinogenic mixtures from native American shamans, he explores these altered states of consciousness and finds that memory, time, and perhaps reality itself are states of mind.
Unfortunately the movie Altered States is not yet available on HBO Max.
