The upcoming sixth season will be the last for NBC supernatural crime drama series Grimm. It will premiere January 6 and run on the show’s regular night, Friday, at 8 PM, an hour earlier than the previous five seasons.

There was an alarm raised in April when Grimm, whose first five seasons consisted of 22 episodes each, only received a 13-episode renewal for Season 6. The series was left on the bench for the first time. Except for 2012 when it launched following the Summer Olympics, Grimm has been debuting just before Halloween.

Grimm had been the little engine that could, an under-the-radar show that became a breakout during the 2011-2012 season despite airing on Fridays. It was the first series launched by the current NBC regime to stick. Last season, the supernatural procedural averaged  a 1.6 most current adults 18-49 rating and 6.0 million viewers. That was down from the Season 5 averages (2.0, 7.1), but Grimm still ranked as one of the highest-rated scripted series on Friday despite being a self-starter, with very little lead-in support. It also is owned by NBC and does well internationally.

As for events leading into the final season, the nefarious forces of Black Claw have been silenced and Nick (David Giuntoli) faces an all too familiar foe in Capt. Sean Renard (Sasha Roiz). Now in the seat of power as the mayor elect of Portland, Renard is poised to bring rise to his own brand of law and order. Nick must take a stand to protect his city and those closest to him, especially his child with Adalind (Claire Coffee). It will take the full force of Nick and his allies to find a way to bring the peace.

Meanwhile, Monroe (Silas Weir Mitchell) and Rosalee (Bree Turner) grapple with bringing a child into a new and tumultuous world, and Eve (Bitsie Tulloch) faces unsettling identity issues as her former self lurks below the surface.

Grimm also stars Russell Hornsby and Reggie Lee.

The series was created by David Greenwalt & Jim Kouf and Stephen Carpenter. Sean Hayes and Todd Milliner serve as executive producers along with Greenwalt and Kouf. Grimm is a Universal Television and Hazy Mills production.
