The FBI's most famous tracker is on the trail of a villain who murders people in order to become the subject of a manhunt.

Rey Mysterio is the number one contender. But can he make it to his championship match at Summer Slam? Find out on an all new Friday Night SmackDown.

8/9c - When the philandering, drug-abusing wife of an arrogant plastic surgeon (guest star Robert Knepper) disappears, Detectives Goren (Vincent D'Onofrio) and Eames (Kathryn Erbe) suspect the doctor's earnest efforts to find her are bogus -- especially when they find he has a lover (guest star Penny Balfour) of his own. But even when the body of a decomposed woman washes ashore weeks later, the cops can't crack the doc's airtight defense -- and their only hope might be to turn his ego against him.

9/8c - When a prominent doctor is murdered at his son's bar mitzvah, Detectives Goren (Vincent D'Onofrio) and Eames (Kathryn Erbe) first suspect the victim's estranged wife but their probe widens when evidence involves a warped forensic psychiatrist (guest star Michael Gross, "Family Ties," NBC's "ER") who wanted to impress the dead man's pretty in-law (guest star Stephanie Seymour, "Pollock"). However, the attempted prosecution turns thorny when the primary suspect craftily makes an unexpected plea.
