Ant-Man and the Wasp follows Hank Pym and Janet Van Dyne using their shrinking technology to prevent it from becoming a weapon. Their quiet work ends when A.I.M. resurfaces under the control of George Tarleton, a brilliant scientist transformed into the enlarged MODOK after an experiment using stolen Pym Particles. MODOK believes evolution has left humanity weak and plans to create a new intellectual order ruled by minds enhanced through technology. To complete his plan, he recruits Elihas Starr, the arrogant genius known as Egghead, who has spent years obsessed with proving he is smarter than Hank. Together, they steal Pym's research and construct a device capable of shrinking sections of cities, giving A.I.M. control through fear. Hank wants to face the crisis alone, but Janet refuses to let him repeat his old mistakes. Their conflict reminds them why they became partners, in the first place! They infiltrate an A.I.M. facility and discover MODOK has captured Bill Foster, Hank's former colleague, forcing him to stabilize it. Hank and Janet race to stop the launch. Egghead betrays MODOK, intending to claim the technology, but MODOK anticipated it and turns A.I.M. against him. During the final battle, Hank becomes Ant-Man and Janet becomes the Wasp, combining shrinking and flight to destroy the machine from within while Bill escapes and disables its power source. Egghead is arrested, but MODOK escapes after Hank defeats his calculations. The film ends with Hank and Janet choosing to work as true partners. A.I.M. is dismantled, but MODOK survives with stolen research.
