What looks like the ritual mutilation of a Jane Doe leads the CSI team to the freakish attractions of a 19th Century-inspired traveling sideshow. The sideshow’s MC/owner, Major Willie, and its most popular performer, a young man named Joseph Merrick, aka "The Elephant Man", are suspects after our team finds out the victim was looking to leave the sideshow. Willie would lose his best earner and Joseph was having a love affair with her. Toxicology reports show that the victim was not killed by the multiple syringes inserted in her body but by a powerful anesthetic Propofol. The cast of sideshow characters makes it tough to know who the likely suspect is but as the investigation develops, the CSIs discover the most dangerous "freak” lurks among us in the real world and the sideshow group was ultimately the victim's real family.
