Just when his time under house arrest is about to end, Scott Lang once again puts his freedom at risk to help Hope van Dyne and Dr. Hank Pym dive into the quantum realm and try to accomplish, against time and any chance of success, a very dangerous rescue mission.

Fulfilling a promise to his deceased father, one-time outlaw Jesse Custer returns home to West Texas to take over his dad's church. Jesse's mission, however, becomes twisted when his body is overcome by a cryptic force that unleashes within him a highly unconventional power. Together with hell-raising ex-girlfriend Tulip and Irish vagabond Cassidy, the preacher-in-training embarks on a journey to find God in a world inhabited by holy, hellish, and everything-in-between characters.
