Considered to be one of the greatest chemists of the 20th century, Sasha's vast array of discoveries have had a profound impact in the field of psychedelic research, making him a subject of fascination and controversy among fellow scientists and a folk hero to recreational users of psychedelics. Dirty Pictures uncovers the lifework of Dr. Shulgin and takes  viewers inside his Northern California home where he lives with his wife of 40 years and continues to carry out experiments in a makeshift laboratory.
