Ant-Man isn't due to come until July 17, but if you simply just can't wait until then to find out what Marvel has done to Scott Lang's story, you can check out the studio's Japanese trailer for the film.
By this time, anyone interested already has more or less a grasp of what will happen in Ant-man. As such, the trailer devotes less time showing the superhero in action, instead choosing to spend more time setting up who Scott Lang is.
Essentially, Scott Lang, played by Paul Rudd, just got out of prison. His ex-wife Peggy Rae has custody of their daughter Cassie. He's working in Baskin' Robbins. He's not free to see his little girl whenever she wants. He wants his life back but mostly he wants to get it together because Cassie is sick. It's actually in trying to do something about Cassie's condition that Scott Lang finds himself meeting Hank Pym, the creator of the Ant-man suit.
