In Ant-Man and the Wasp: Quantumania, when Cassie (Kathryn Newton), daughter of Scott Lang (Paul Rudd), develops a device that would allow communication with the quantum realm, the experiment ends in disaster: Cassie, Scott and their companion and heroine, Wasp, Hope van Dyne (Evangeline Lilly) unwittingly find themselves in the mystical realm. Joining forces with Hope’s parents, Hank Pym (Michael Douglas) and Janet van Dyne (Michelle Pfeiffer), the trio works their way back as they lure them into the mysterious world of the Quantum Realm, where they encounter alien creatures and a hidden civilization. They also discover that Janet, who has been trapped here for 30 years, is still hiding a secret or two from her past: why the mysterious Kang (Jonathan Majors), who has the ability to pass, is also trapped in the quantum, the dimension used to travel through time and the multiverse? And most importantly, why does he need Scott’s help on an important mission? Can the mighty Kang be trusted?
