Cat burglar Scott Lang is released from San Quentin Penitentiary and resolves to go straight for the sake of his daughter. Inventor Dr Hank Pym invites Scott to don a superhero outfit, which shrinks the wearer at the touch of a button. Aided by Hank's feisty daughter, Scott masters the suit and learns to mind-control four species of ants. Humans and insects take on Hank's former protege, Darren Cross, who intends to sell the Ant-Man technology to the highest bidder.
