X-Force is back! The original team has reassembled, better and badder than ever before, to honor the memory of their fallen founder, the man called Cable! But Cable´s killer is his own past self - a much younger Nathan Summers, who traveled back from Cable´s apocalyptic future decades earlier than he should have and eliminated his adult self for failing to adhere to their lifelong mission. And that little paradox makes things tough for X-Force! The team barely survived a vicious face-off against Ahab, another time-traveling menace - but how will they react when they learn that someone else has followed "kid Cable" back from his future?
