Excalibur moves in together! But before they can say “team bonding exercise”, the Juggernaut attacks! Cain Marko has broken out of prison and is on a rampage across Europe. But why? Can this new team take down the Unstoppable One?
A lady by the name of Vixen has broken into Her Majesty's Ultra Maximum Prison, Crossmoor, accompanied with her own secret "guard." After money they plan on breaking out a prisoner, but are encountered by the police. They stumble upon the Juggernaut, and free him as a distraction. Vixen and her men escape.
Meanwhile, with Juggernaut on the loose Excalibur comes to help. They split up attempting to sedate Juggernaut and any other escapees. Meanwhile an unknown man seeming to be an alien enthusist finds some unknown technology ending with very unusual results.
After all the fighting, the spotlight is back on Excalibur as they are seen moving to a new base, but odd events are occuring, and Captain Britain is having some trouble with some personal issues.
