Scott Lang -- the Astonishing Ant-Man -- has a new life in New York City with his daughter, Cassie. Scott's determined to make it work: Cassie's in a good school, he's got a steady job, and he's finally ready to explore that wide, safe, non-spandexed dating world. But despite his best intentions, Scott just can't stay out of the spotlight -- or magnifying glass -- and it doesn't take long for his new life to fall apart. When an old partner-in-crime goes to trial, Scott and Cassie are stuck with federal bodyguards. Scott is convinced the protection is unnecessary, but he hasn't calculated the teenager factor! When trouble finds Cassie, Scott throws caution to the wind and dons the suit. But what is the villain really after?
