Entourage's Adrian Grenier, Rescue Me's Denis Leary
TV's sizzling summer season has saved its best for last. Here's our guide to the season enders you will not want to miss.

Entourage, HBO
Finale airs Sunday, Sept. 2, at 10 pm/ET
"Medellin" — triumph or fiasco? That's the question that Entourage has been asking during its fourth season, which began with prettyboy movie star Vincent Chase (Adrian Grenier) on the set of the violent Spanish-language film about drug lord Pablo Escobar. "We'll get lots of answers," promises exec producer Doug Ellin. The season finale was shot on location at the Cannes Film Festival last May. "Scenes took place live during the Ocean's Thirteen premiere, so our guys had to get their lines down while crowds were screaming." Post-finale, Entourage goes on hiatus until June. And then? "I have not a single idea," says Ellin, laughing.

The Bill Engvall Show, TBS
Finale airs Tuesday, Sept. 4, at 9 pm
The season goes out with a song when Bill (Engvall) and wife Susan (Nancy Travis) visit a karaoke bar, where she does her best Pat Benatar. The lesson, says Engvall: "Sometimes our minds think we're younger than we are." No cliff-hanger, though. "If, god forbid, we don't get a renewal, people will sit there and say, ‘What was that?'" (See Bill Engvall's TVGuide.com celebrity blog for more.)

State of Mind, Lifetime
Finale airs Sunday, Sept. 9, at 8 pm
Who's your daddy? That's the question Ann (Lili Taylor) will be asking when she finds out she's pregnant but doesn't know if the father is ex-husband Phil (Chris Diamantopoulos) or recent fling William (Courtney B. Vance). And she's not the only doc dealing with drama. James (Derek Riddell) finds out his father's been kicked out of his retirement home and turns to his colleagues to help parent-sit until he can solve his own daddy drama.

My Boys, TBS
Finale airs Monday, Sept. 10, at 10:30 pm
Chicago sportswriter PJ (Jordana Spiro) will decide what to do with the extra plane ticket to Italy she's been holding on to all season. Will the lucky recipient be a guy? "Who knows?" says Spiro, with an insider's laugh. As for next season: Spiro hopes Cubs beat reporter PJ will take the next step at her job. "She covers only one sport, but I would love it if she became a columnist and she could cover different sports. I would really love it if she'd start covering the Bears."

Rescue Me, FX
Finale airs Wednesday, Sept. 12, at 10 pm
After a fall off the wagon, Tommy (Denis Leary) joined sister Maggie (Tatum O'Neal), Uncle Teddy (Lenny Clarke) and some cousins to form a Gavins all-star AA team. Now, even as Papa Gavin (Charles Durning) drinks, father and son bond over two things more American than whiskey — baseball and roller coasters.

Monk, USA Network
Finale airs Friday, Sept. 14 at 9 pm
Donal Logue guest-stars as a grifter, but the big news is Monk's other chance encounter. Says star Tony Shalhoub, "He literally bumps into a woman on the street. She's a total stranger, but he can't get her out of his head. I don't want to give too much away, because it's a poignant ending." Maybe a setup for romance when the show returns in January? "It may be time to open that door," Shalhoub says. "And not a moment too soon."

Psych, USA Network
Finale airs Friday, Sept. 14 at 10 pm
Kevin Sorbo (Hercules) guest-stars as a hotshot bounty hunter once idolized by detectives Shawn (James Roday) and Gus (Dulé Hill). Now he's the competition. The kicker? A Midnight Run-style race to find a suspect. "We've always wanted to do a big, spectacular, high-action episode," says creator Steve Franks, "so we hired John Badham [WarGames] to direct, and we've just gone crazy."
