Armed with a super-suit in order to shrink in scale but increase in strength, cat burglar Scott Lang must embrace his inner hero and help his mentor, Dr. Hank Pym, plan and pull off a heist that will save the world.
Scott Edward Harris Lang, a former criminal who was convinced by Pym Technologies CEO Hank Pym to take up his mantle as the new Ant-Man.
As time goes by he joined the Avengers team and fought alongside Captain America after being recruited by Falcon, whom he had previously met before defeating Cross. Being imprisoned for a few times he was then freed by Captain America. He, along with Hawkeye, returned to a normal life by making a deal with Thaddeus Ross of the United Nations, which resulted in him being placed under house arrest.
Ant-man remained under house arrest after 2 years, spending much of his time playing with his daughter and learning magic tricks. One day near the end of his sentence, Lang received a dream from Janet van Dyne in which he saw a younger Hope. Lang notified Pym and Hope, who were on the run because of the Sokovia Accords. Hope, now having taken up the mantle of Wasp, broke Lang out of his home whilst successfully evading police detection, and took him to her father's portable lab. At Pym's lab, the three learned that Lang was quantumly entangled with Janet, and that they had a limited amount of time to retrieve her from the Quantum Realm. Ava Starr, and Bill Foster, a former colleague of Pym's, sought to steal the lab, and use Janet's energy to heal Ava of her intangibility and pain. Sonny Burch, a criminal businessman also sought out the lab for its advanced technology. Together Lang and Hope were able to fight them off while Pym went into the Quantum Realm himself, successfully saving his wife. Upon her return, Janet was able to heal Ava. Lang finished his sentence, and was no longer under house arrest.
While he was in the Quantum Realm, Thanos succeeded in gaining all six Infinity Stones and wiped out half of all life in the universe to complete his quest. During a countdown before his return, Pym and the van Dynes were all turned to dust, leaving Lang stranded in the Quantum Realm.
