"Alias" (8 p.m., WXYZ-TV, Channel 7, ABC). Chips ahoy! It’s a case of too much espionage monkey business for Sydney (Jennifer Garner) when a mysterious microchip implanted in Renee’s (Elodie Bouchez) skull is tied to So Not Dead Vaughn (Michael Vartan). Meanwhile, Sloane (Ron Rifkin) sees dead people as he slips back into sinister mode, working for Prophet Five, the latest cartel of creepy evil to turn Syd vicious.

Bruce and Cybill redux?

"Bones" (8 p.m., WJBK-TV, Channel 2, Fox). Opposites attracting. The bickering, bantering chemistry shared by no-nonsense forensic anthropologist Temperance (Bones) Brennan (Emily Deschanel) and rugged FBI agent Seely Booth (David Boreanaz) has given the clever first-year crime procedural an extra bit of witty zing. Tonight, while solving the mysterious murder of an Iraq war veteran, the Bones-Booth relationship heats up. Let’s just hope the producers aren’t flirting with a "Moonlighting" disaster.

’Jeopardy!’ it isn’t

"Criminal Minds" (9 p.m., WWJ-TV, Channel 62, CBS). Season finale. It’s a psycho killer cliffhanger. A relaxing vacation break for profiler Jason Gideon (Mandy Patinkin) and other members of the FBI Behavioral Analysis Unit is agonizingly interrupted by the homicidal maniac du jour. The demented one sends Gideon & Co. clues in a macabre fantasy game that must be unraveled to save the life of the killer’s next victim. The designated victim is a screaming, terrified woman in shackles as we pay yet another grim visit to the Planet of Women in Extreme Jeopardy. The really disturbing part? "Criminal Minds" is a hit.

Other-wise...

"Lost" (9 p.m., WXYZ-TV, Channel 7, ABC). Twisted mister. So what the bloody heck is going on here? Is Michael (Harold Perrineau) now one of those infernal Others? It sure looked like it after last week’s cosmic shocker when Michael suddenly gunned down Ana Lucia and Libby (Michelle Rodriguez, Cynthia Watros). And are they really dead? On "Lost," any loony thing is possible as Jack (Matthew Fox) and the other survivors struggle to cope with the hatch horror.

Play it again, L&O

"Law & Order" (10 p.m., WDIV-TV, Channel 4, NBC). Moonlighting. Michael Imperioli of "The Sopranos" takes another break from mob life to play Detective Nick Falco, who filled in for Detective Ed Green (Jesse L. Martin) last season. Now Falco’s in big trouble. He’s suspected of murder after he wakes up in his apartment and finds the body of the hottie he had a date with the night before.

Hmm, this could be a plotline pilfering misdemeanor; "Crossing Jordan" had a similar story Sunday.

Listen up, pilgrims

"American Masters" (10 p.m., WTVS-TV, Channel 56, PBS). Quality alert. "American Masters" kicks off its 20th season with "John Ford/John Wayne: The Filmmaker and the Legend," an enthralling portrait of how famed director John Ford helped transform a B-movie actor named John Wayne into an American icon. The two collaborated on 14 films, including such epic Westerns as "Stagecoach," "Fort Apache" and "The Searchers." A mesmerizing chapter of Hollywood history. Excellent.
