A woman is left naked inside a duffel bag on Times Square, completely covered in recent tattoos, among which is the name of FBI Special Agent Kurt Weller. She suffers from a drug-induced amnesia. At the FBI laboratory, they can neither identify her, nor does Kurt know her, making her a Jane Doe. They also find an older Navy SEAL tattoo that was covered up. One of her tattoos is an address in Chinese characters, leading them to the terrorist Chao. Jane and Kurt stop him, which triggers a memory of Jane running a shooting course supervised by an unknown man. This man also appears at the hospital to kill Chao. A flashback shows how the same man has given Jane the amnesia drug at her request. A number on Jane's body matches a redacted file of Assistant Director Bethany Mayfair.
