It starts off Scott Lang doing a heist, getting caught and sent to prison for around 2 years. Then he gets out he was picked up bu Hank Pym and his daughter Hope Van Dyne. He is given a second chance by both of them and given the chance to become Ant-Man stop Yellowjacket. He also lets Hope become the wasp but is unwilling at first because as the audience later find out that in the 60's Hank and Janet were the Ant-Man and Wasp and that they both worked for S.H.I.E.L.D and Janet died on a mission. Hank doesn't trust S.H.I.E.L.D anymore. There a Nick Fury cameo in the end credits scene.This is part of the Marvel Cinematic Universe (MHM15).
