First Look Photo at Keegan Allen From 'Walker' Series Premiere!

Keegan Allen stars in this first look photo from the upcoming series premiere of his new show Walker!

The 31-year-old former Pretty Little Liars actor stars as Cordell Walker’s (Jared Padalecki) younger, gay, conservative brother William, aka Liam.

Also featured in new stills from the premiere include Cordell, Walker’s parents – Abeline Walker (Molly Hagan) and Bonham Walker (Mitch Pileggi), his kids August Walker (Kale Culley) and Stella Walker (Violet Brinson), late wife Emily Walker (Genevieve Padalecki), as well as Trey Barrett (Jeff Pierre), Micki Ramirez (Lindsey Morgan), and Captain Larry James (Coby Bell).

Here’s a synopsis for the premiere episode: Texas Ranger Cordell Walker (J Padalecki), a widower and father of two with his own moral code, returns home to Austin, TX, after being undercover for two years, only to discover there’s harder work to be done at home.

As Walker attempts to reconnect with his creative and thoughtful son August (Culley) and his headstrong, somewhat rebellious teenaged daughter Stella (Brinson), he finds that he needs to navigate clashes with his family – Liam (Allen), Walker’s ADA brother who stepped in during Walker’s absence, his perceptive mother Abeline (Hagen) and his traditional rancher father Bonham (Pileggi).

Walker’s former colleague, Larry James (Bell), is now his Ranger Captain. And Walker finds unexpected common ground with his new partner Micki Ramirez (Morgan), one of the first women in Texas Rangers’ history while growing increasingly suspicious about the circumstances surrounding his wife’s death (G Padalecki).

Walker will premiere on Thursday, January 21st at 8pm ET/PT. Watch the trailer here!
