The cast and EPs tease the fourth and final season in this exclusive video

Halt and Catch Fire type TV Show network AMC

Halt and Catch Fire‘s goodbye tour is about to begin.

In the exclusive behind-the-scenes video above, the cast and executive producers of the criminally under-viewed AMC techno-drama preview the series’ final season. Set in the ’90s, season 4 follows Joe (Lee Pace), Cameron (Mackenzie Davis), Donna (Kerry Bishé), and Gordon (Scoot McNairy) as they take on the world of search at the dawn of the internet age. However, they won’t be alone in their quest; the new season features both new and familiar faces.

In the new season, we have Veep‘s Anna Chlumsky, who joins the show as Dr. Katie Herman, the chief ontologist assisting Gordon and Joe with their latest business venture. The Emmy-nominated actress promises there’s more to her new character than meets this eye.

“She’s got this full-of-surprises quality to her,” Chlumsky teases in the video above.

This season will also feature Gordon and Donna’s children as teenagers. We already met Kathryn Newton (Big Little Lies, Supernatural) as Joanie in the exceptional third season finale, and this season, we’ll encounter the other Clark child, the introverted Haley (Susanna Skaggs), who shares “that computer brain that initially brought Gordon and Donna together,” says co-creator and EP Christopher C. Rogers, adding that she wanders into the business.

Overall, you can expect the final season to take stock of everything these innovative characters have created since the series premiere. “Halt and Catch Fire has always been the story of how people put themselves into the things they create. I think the fourth season is very much the story of how the things people create change them,” says Rogers.

Watch the video above to see Pace, Davis, Bishé, and McNairy preview what’s in store for their characters this season.

The final season of Halt and Catch Fire begins with a two-hour premiere Saturday, Aug. 19 at 9 p.m. ET on AMC. The first three seasons are now streaming on Netflix.
