A young mutant boy with the power to erase memories with a flash of light is recruited by the Men in Black, placed under the guidance of agents J and K. What should have been a controlled weapon becomes something far more dangerous when missions start collapsing into contradictions—and enemies seem to know secrets no one remembers telling them. As reality fractures and trust inside MiB begins to rot, one question rises above all others in J & K's minds: Who is the real enemy… when no one can trust their own mind?
