This is the main story line for the Marvel Civil War event. It will give you the important plot points, but you'd need to read the tie-in issues to get the full depth and breadth of the story arc. Fortunately, Marvel has compiled a reading list/order for their Civil War event. I've read them in that order and loved the whole series. Particularly notable is the incident that starts things in motion and the issues it raises for the Marvel universe heroes.
