The Umbrella Academy has one last chance to save the timeline.

Netflix released the season four trailer for one of the streamer’s most popular shows on Tuesday, teasing the group embattled in one last mission to save the world.

Among others, Nick Offerman will join the season four cast, and fans catch glimpses of his character in the new trailer. “The world we live in is one big phony baloney lie,” he says in a voiceover. “That tentacle boy is the key to understanding all the timelines.”

It appears Offerman’s character is referring to Ben, played by Justin H. Min, whose character’s back-from-the-dead storyline will feature heavily in season four.

The new installment, set for release in August, will begin after season three’s major showdown at the Hotel Oblivion, which reset the group’s timeline and left the original siblings stripped of their powers. Now, they must “fend for themselves and find a new normal with wildly varying degrees of success,” the show’s description reads. “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.”

At the same time, “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.”

Originally based on the Dark Horse comic book series by Gerard Way and Gabriel Bá, The Umbrella Academy stars Elliot Page, Tom Hopper, David Castañeda, Emmy Raver-Lampman, Robert Sheehan and Aidan Gallagher as the original set of six siblings. Min, Ritu Arya, Colm Feore, Offerman, Megan Mullally and David Cross round out the main cast of the fourth season of the series, from UCP, a division of Universal Studio Group.

The trailer comes a week after Steve Blackman, co-creator of the series, was accused of alleged bullying and harassment by 12 anonymous sources in a Rolling Stone report. Blackman, via his rep, issued a statement to Rolling Stone dismissing the accusations, and The Hollywood Reporter was sent pieces of this statement last week from Blackman’s representative, who asserted, “The allegations were thoroughly investigated and all but one were found to be unsubstantiated because they are entirely untrue.”

The Umbrella Academy‘s final season will release to Netflix on Aug. 8.
