AMC has announced that the first trailer for the upcoming "Walking Dead" spinoff will air during its parent show's 90-minute season five finale (hat tip to Access Hollywood).

The still untitled series has already been picked up for two seasons by the network. The first six-episode season is scheduled to debut at some time this summer with a follow-up season expected to air in 2016. While the premise behind the series has been kept under wraps, it is said to take place in Los Angeles before the apocalyptic zombie outbreak.

The series will star Cliff Curtis as divorced teacher Sean Cabrera and Kim Dickens as the female lead, a guidance counselor named Nancy. Frank Dillane and Alycia Debnam Carey are also attached to star as Dickens' children, Nick and Ashley. Adam Davidson, who previously helmed episodes of "Friday Night Lights" and "Fringe," directed the recently-wrapped pilot. The companion series will be executive produced by "The Walking Dead's" Kirkman, Dave Erickson, Gale Anne Hurd and David Alpert.

"The Walking Dead's" season finale, an episode titled "Conquer," airs this Sunday on AMC.
