The game is in the fourth quarter for "Friday Night Lights."
For nonfans, it might seem more like overtime.
"Lights" is beginning its fifth season on NBC, leading to the series finale for the best drama on network TV.
For the loyal, this last season (which already aired on DirecTV, but gets its network run beginning at 8 p.m. EDT Friday) will be a roller-coaster ride.
The opener starts on a bittersweet note: Newly graduated Julie (Aimee Teegarden) bids farewell to Dillon, Texas, and moves on to college. She finds life there, without the wisdom of her parents to keep her in check, to be quite the experience.
Meanwhile, Julie's dad, high-school football coach Eric Taylor (Kyle Chandler), tackles another season with a team in disarray. He has high hopes for a winning season, but keeping his players out of trouble is a full-time job.
Julie's mother, high-school principal Tami Taylor (Connie Britton), has her hands full as well. She takes a wayward student under her wing, trying to set the girl back on the right path.
Bad boy Tim Riggins (Taylor Kitsch) won't be around much this season since he was sent to prison at the end of last season. However, his presence will be felt in several stories.
The season will also see the return of many original cast members, including Scott Porter, Adrianne Palicki and Zach Gilford.
