After fleeing his predetermined life, a young man named Jack survives a plane crash only to discover an underwater utopia called Rapture, now a decaying nightmare. Guided by a mysterious Irishman named Atlas, Jack is hunted by mutated addicts called Splicers. He injects a powerful substance called ADAM to survive, unlocking hidden combat skills he never knew he possessed. As he fights to escape, Jack uncovers a devastating truth: his entire identity is a fabricated lie implanted by Atlas. His real father is Rapture’s tyrannical founder, Andrew Ryan, and the trigger phrase “would you kindly” forces him to obey any command, forcing Jack to commit patricide before confronting his puppet master in a final, monstrous battle for freedom.
