It is a spin-off of another Fox television series, Bones.
The backdoor pilot, entitled "The Finder", aired in its sixth season.
Alongside Special Agent Judy Green (guest star Ever Carradine), Walter and Leo find clues leading to a counterfeit money ring.
Meanwhile, Leo enlists Isabel's help in looking after Willa. Jack Hodgins ropes Walter into searching for an 'Alien' spacecraft videotaped by an incoming space shuttle pilot, who is now dead. Bradshaw, whose reputation was harmed by a shadowy government agency for participating in the disclosure, lies in the balance.
After discovering that a painting he found four years prior was a forgery, Walter begins searching for the original, but Walter's brother Langston shows up with news that their father is dying.
