It’s one final world-saving mission for David Castañeda.

Netflix has released the final trailer for the fourth and final season of its time-travel drama The Umbrella Academy, starring the 34-year-old Mexican American actor.

The trailer offers a glimpse of Nick Offerman’s character as Dr. Gene Thibedeau.

“The world we live in is one big phony baloney lie,” Offerman’s Thibedeau is heard in a voiceover. “That tentacle boy is the key to understanding all the timelines.”

Tentacle boy is an apparent reference to Justin H. Min’s Ben Hargreeves, who died during a mission but whose storyline appears to be a focus in Season 4.

Created by Steve Blackman, based on Gerard Way and Gabriel Bá’s Dark Horse comic book series, The Umbrella Academy’s final chapter launches August 8 on Netflix.

In the upcoming final season, the Hargreeves siblings have scattered after the climactic showdown at the Hotel Oblivion led to a complete reset of their timeline. Stripped of their powers, each is left to fend for themselves and find a new normal — with wildly varying degrees of success. Yet the trappings of their uncanny new world prove too hard to ignore for very long. Their father Reginald, alive and well, has stepped out of the shadows and into the public eye, overseeing a powerful and nefarious business empire. A mysterious association known as The Keepers holds clandestine meetings believing the reality they’re living in is a lie and a great reckoning is coming. As these strange new forces conspire around them, the Umbrella Academy must come together one last time — and risk upsetting the shaky peace they’ve all endured so much to secure — to finally set things right.

In addition to Castañeda and Min, Season 4 returning cast includes Elliot Page, Tom Hopper, Emmy Raver-Lampman, Robert Sheehan, Aidan Gallagher, Ritu Arya, Colm Feore, Megan Mullally and David Cross.

The Umbrella Academy is produced by UCP, a division of Universal Studio Group, for Netflix.
