The series premiere of the HBO series “Watchmen” debuted Sunday night and while the show is inspired by some fictional characters in the DC Comics series of the same name, the plot of the first episode was all too real.

Set in an alternative history where superheroes are seen as outlaws, the initial episode sees Detective Angela Abar and Chief Judd Crawford look into the attempted murder of a Tulsa police officer in 2019 — where law enforcement now shields their faces with masks. The probe comes nearly 100 years after a Black boy and an orphaned baby girl are the lone survivors after planes drop bombs on the community in the 1921 Tulsa Race Massacre.

The 20th-century incident saw the Ku Klux Klan invade the area of Black wealth known as Black Wall Street on May 31, 1921, and kill at least 300 people — 90 percent of whom were Black. Over the course of 16 hours, the community was left in shambles, burned to the ground after white mobs destroyed 35 city blocks where 1,200 people lived. Moreover, 600 thriving businesses were lost, and among them were 30 grocery stores, 21 restaurants, two movie theaters, and a hospital.

The moment has been deemed the “single worst incident of racial violence in American history, “ according to the Oklahoma Historical Society.
