Scott Lang, played by Paul Rudd, is trying to embrace a quiet life as a hero and a father, but his peaceful days are shattered when a scientific experiment with his daughter Cassie, portrayed by Kathryn Newton, goes awry. The entire family—including Hope van Dyne (Evangeline Lilly) and her parents, Michelle Pfeiffer as Janet van Dyne and Michael Douglas as Hank Pym—is thrust into the bizarre and unpredictable Quantum Realm. This hidden universe beneath reality is filled with strange creatures and empires, but their exploration is cut short by a terrifying discovery. They encounter the mysterious and formidable Kang the Conqueror, brought to life with chilling intensity by Jonathan Majors, a being with immense power and a dangerous agenda that threatens all of reality. Directed by Peyton Reed, this sci-fi adventure blends spectacular action and signature humor as Ant-Man and the Wasp must navigate this surreal landscape and rally unexpected allies to face a threat far greater than anything they have ever encountered.
