The Umbrella Academy is set in a universe where forty-three women around the world give birth simultaneously at 12:00 PM on October 1, 1989, despite showing no signs of pregnancy until labor began. Seven of the children are adopted by eccentric billionaire Sir Reginald Hargreaves and turned into a superhero team that he calls “The Umbrella Academy.”
Hargreaves gives the children numbers rather than names, but they are eventually named by their robot-mother, Grace, as Luther, Diego, Allison, Klaus, Five, Ben, and Vanya.While putting six of his children to the task of fighting crime, Reginald keeps Vanya apart from her siblings’ activities, as she supposedly demonstrates no powers of her own.
The first season is set in the present day, where Luther is part ape and has lived on the moon for four years, Allison is a famous actress, Vanya is a violinist, Klaus has an addiction, Five is missing, having disappeared sixteen years earlier, Ben, now deceased, is a ghost able to converse only with Klaus, and Diego has become a vigilante with a penchant for trouble. The estranged siblings learn that Reginald has died and gather for his funeral. Five returns from the future, revealing that a global apocalypse is imminent, but is chased by time-travelling operatives Hazel and Cha-Cha. Meanwhile, the reunited siblings try to uncover the secrets behind Reginald Hargreaves’ life, as their dysfunctional relationships are strained further.
The second season takes place immediately after the first season. Failing to stop the apocalypse, the siblings are forced to travel back in time, but it goes awry, scattering them across different years in 1960s Dallas. Five ends up on November 25, 1963, in the middle of a nuclear doomsday, but with the help of Hazel manages to travel back ten days. While being hunted by a trio of Swedish assassins, Five finds his siblings, who have each made new lives, and attempts to reunite them in order to stop this new apocalypse.
