A decomposing body is found by a couple of show dogs who get loose and run into the woods. When one of the owners tries to stop Hodgins from shaving her dogs coat for evidence, he accidentally ends up shaving off his own eyebrow. He tries to make a fake eyebrow but it won’t quite stay in place.
The victim is Ian Goldberg, a pioneer in artificial intelligence. He designed robots to work with autistic children. Ian’s body was badly damaged by being dragged through the woods after he was killed. AMI his AI robot is questioned but her memory was wiped by Ian the day he was killed.
Evidence leads Booth and Aubrey to a company that makes sex dolls. Turns out Ian was about to make a deal to put his artificial intelligence into the dolls. The idea came from his friend Randy, a naturalist/druggie whom Ian used to meet in the woods to smoke pot and use LSD to increase his creativity.
Randy thought he would make millions on the sex dolls because integrating the AI was his idea. When Ian only gave him a blue tooth speaker as a gift, he flew into an LSD induced rage. He stabbed Ian multiple times int he neck with his pocket knife, tried to string him up in a tree to hide the body and then dragged him through the woods. Booth and Aubrey arrest him for murder.
