“Is God Is” is an R-rated suspense revenge thriller that adapts playwright Aleshea Harris’s story for the screen. The film centers on twins Racine and Anaia, played by Kara Young and Mallori Johnson, who still carry scars from a house fire that nearly killed them when they were children. The blaze led to foster care and years of isolation and stigma. Their lives shift when a letter reaches them from their mother, Ruby (Vivica A. Fox), whom they believe died in the fire. Ruby is now in poor health after surviving severe injuries and explains that the fire was not an accident but the result of domestic violence perpetrated by their father. She asks her daughters to kill him—presented as “real dead”—to avenge what he did. As the sisters deal with their differing temperaments and trauma, Racine becomes more eager to take action while Anaia hesitates. Directed as a tense, character-driven journey, the film depicts their pursuit of closure and revenge, with performances from Young, Johnson, A. Fox, and Sterling K. Brown anchoring the story.
