Plot summary
Howard, Claude, and Seale arrive at the scene; Seale charges Jack and is promptly shot dead. Andy attempts to drive away for help, but Jack shoots him as well, then shoots the gas tank of the vehicle Andy was driving. Howard tries to rescue Andy, but Jack ignites the gasoline, killing them both. When the entity commands Jack to kill Holly, Jack refuses. He approaches the others, begs them to kill the entity, then commits suicide. Ralph and Holly enter the cave and find the entity, who expresses disbelief that Holly discovered the truth about it.
It offers few details when Holly inquires about its history and nature. Claude enters and shoots the entity, causing the cave to collapse; the entity is impaled by falling debris. Before the three exit the cave, Ralph encounters a vision of his dead son. He determines the entity has not died, so he returns to it. He berates it, then sees it attempt to transform further. Ralph crushes its head with a large rock. Yunis contacts Hayes and implicates Jack and the entity. Claude and the investigators, with help from Jeannie and Glory, coordinate their stories.
Hayes holds a press conference to exonerate Terry and reopen Frankie's case. In a mid-credits scene, Holly is shown to have the same cut on her arm that the entity gave to its other victims.
