In 1987, Janet van Dyne shrinks between the molecules of a Soviet nuclear missile, disabling it but entering the microscopic quantum realm. Hank Pym raises their daughter Hope believing that Janet is dead.
Years later, former criminal Scott Lang takes up the mantle of Ant-Man and discovers a way to both enter and return from the Quantum Realm. Pym and Hope begin work on repeating this feat, believing they may find Janet alive.
Lang and Hope also start a romantic relationship and begin training to fight together as Ant-Man and the Wasp, until Lang secretly helps Captain America during a skirmish between the Avengers in violation of the Sokovia Accords. Lang is placed under house arrest, while Pym and Hope go into hiding.
Two years later, Pym and Hope briefly manage to open a tunnel to the quantum realm. Lang receives an apparent message from Janet, who he is quantumly entangled with. Despite having only days left of house arrest, Lang decides to call Pym.
Hope kidnaps Lang, leaving a decoy so as not to arouse suspicion from the FBI agent Jimmy Woo. Seeing the message as confirmation that Janet is alive, Pym and Hope work to create a stable tunnel so Hope can take a vehicle to the quantum realm and retrieve Janet.
Hope arranges to buy a part needed for the tunnel from black market dealer Sonny Burch, but Burch has realized the potential profit that can be earned from Pym and Hope's research and double-crosses them. Hope fights Burch and his men off, until she is attacked by a quantumly unstable masked woman, referred to as the Ghost. Lang tries to help fight off the Ghost, but she escapes with Pym's portable lab.
Pym reluctantly visits his estranged former partner Bill Foster who helps them locate the lab. The ghost restrains Lang, Hope, and Pym when they arrive, and reveals herself to be Ava Starr. Her father Elihas Starr, another former partner of Pym's, accidentally killed himself and his wife during a quantum experiment that caused Ava's unstable state.
Foster reveals that he has been helping Ava after the accident, who they plan to cure using Janet's quantum energy. Believing that this will kill Janet in the Quantum Realm, Pym refuses to help them and the trio manage to escape.
Opening a stable version of the tunnel this time, Pym and Hope are able to contact Janet who gives them a precise location to find her, but warns that they only have two hours before the unstable nature of the realm separates them for centuries.
Burch learns their location from Lang's business partners Luis, Dave and Kurt, and informs a contact at the FBI. Luis warns Lang, who rushes home before Woo can see him breaking his house arrest. This leaves Pym and Hope to be arrested, and for their lab to be taken by Burch.
Lang is soon able to help Pym and Hope escape custody, and they steal the lab back from Burch. Lang and Hope distract Ava while Pym enters the quantum realm to retrieve Janet, but end up fighting Burch and his men allowing Ava to begin the process of taking Janet's energy.
Luis, Dave, and Kurt help apprehend Burch, so Lang and Hope can stop Ava. Pym and Janet arrive safely from the quantum realm, and Janet voluntarily gifts some of her energy to Ava to temporarily heal her. Lang returns home once again, in time for a suspicious Woo to release him at the end of his house arrest. Ava and Foster go into hiding, but Pym, Lang, Hope, and Janet plan to harvest quantum energy to continue helping Ava.
In a mid-credits scene, Pym, Hope, and Janet all disintegrate, in tandem with the Battle of Wakanda while Lang is harvesting more quantum energy; without anyone to let him out, Lang remains stuck in the Quantum Realm.
In the post-credits, the oversized ant is found playing a drum kit in Lang's house.
