After a gamma creature similar to Hulk attacks General Ross, Bruce Banner is forced to flee to Canada. Knowing his innocence, Betty Ross and Rick Jones hire the Unity Squad to help prove Bruce had nothing to do with the attack. Meanwhile in Canada, Banner encounters Wolverine, who is searching for clues about his past. After a battle, the two decide to stick together to figure Bruce’s problems out. Soon both parties find hints that this is all a plan by scientist Samuel Sterns, who was damaged in the same bomb that created Hulk, now known as the Leader.
