On one day in 1989, 43 infants are inexplicably born to random, unconnected women who showed no signs of pregnancy the day before. Seven are adopted by billionaire industrialist Sir Reginald Hargreeves, who creates the Umbrella Academy and prepares his "children" to save the world. In their teenage years, though, the family fractures and the team disbands. Fast forward to the present time, when the six surviving members of the clan reunite upon the news of Hargreeves' passing. They work together to solve a mystery surrounding their father's death, but divergent personalities and abilities again pull the estranged family apart, and a global apocalypse is another imminent threat.
