The Invisible Man

Darien Fawkes is a con-man and thief who is captured for a third time. Rather then face California's three-strike law, he volunteers for an experiment conducted by his brother Kevin. Kevin and another scientist, Arnaud, have created a synthetic gland that secrets ""Quicksilver"", a substance that can bend light. They place the gland in Darien's head. He soon realizes what has happened and is none too pleased. Darien is even less happy when they discover the gland secretes Quicksilver into the recipient's brain, and enough of it drives the person insane. Darien learns to control his abilities, and soon discovers that Arnaud is up to something. Arnaud claims Darien is insane when he accuses the scientists, but then Arnaud's mercenaries break in, steal the information on the gland, and kill everyone except Darien. Darien goes to his ex-girlfriend, a doctor who is furious at him because he didn't reveal his past. She refuses to believe he can turn invisible, and then Darien is taken away by

Going to Mexico to investigate Arnaud, Bobby meets his new partner Bobby Hobbes: a veteran spy and near basket-case. They escape an ambush by French-Canadian spies. Meanwhile, Arnaud has had Darien's girlfriend Casey brought down to Mexico, planning on using her as a hostage. Darien goes to rescue her, prepared to kill Arnaud since Darien thinks he'll be going insane shortly. Arnaud plays his trump card: there's a counter-agent that will stave off Quicksilver madness, and he'll give it to Darien if he works for him. Darien refuses, escaping with Casey and blowing up the compound (although Arnaud escapes). Both the counteragent and the formula are destroyed, and Darien goes to visit his brother's grave one more time before going permanently insane. However, the Official meets him there and reveals that his Agency was working with Kevin, and they have the counter-agent as well. As long as Darien works for them, he'll get regular doses of the Counter-Agent. Reluctantly, Darien agrees.

A patient in a coma hidden away at a secret hospital recovers and escapes, killing the guards in the process with a poisonous touch. The Agency is called in to investigate, and Darien soon learns that the patient, a ""Catevari"" (named after a Latin story of a woman fed poison until her very touch was poisonous) was another experimental subject of the Agency, like himself. The Catevari goes after the The Official, and Darien manages to save his life by quick use of the freezing properties of Quicksilver. Darian ultimately confronts Catevari, who confronts him with the fact that they both have been messed up by the Agency and should join forces. Fawkes reluctantly decides to stick with those who have helped him, and the Catevari is killed.

A young girl is a witness to an assassination by a sniper. Traumatized, she only speaks to her imaginary friend ""Ralph."" Darien, using his powers of invisibility, convinces the girl he is ""Ralph"" and tries to get her to talk about the murder. Eventually the hit man tries to kill the girl, and Darien manages to stop him. With his help, the girl starts to recover from her trauma, and leaves her ""imaginary friend"" behind.

The Official is forced to resign because of Darien's screw-up, and he and Hobbes have a new boss to deal with.

Darien is contacted by his former mentor and partner, Liz, who wants his help. She wants him to return to his thieving ways and help her steal some FBI files on a mobster who has hired her. Initially reluctant, Darien eventually grows aggravated with the Agency's treatment of him and links up with her. Covertly using his powers of invisibility, Darien manages to get hold of the files, only to realize that the mobster plans to use them to kill a government witness against him. Darien tries to thwart the mobster and keep Liz safe, and manages to do so. The two of them part on relatively friendly terms.

Darien comes to the aid of a female scientist who may be able to remove the Quicksilver gland.
