This series deals mostly with the supposedly-dead assassin Julien coming back to do some serious damage to the Thieves, and to Gambit. On top of that, Gambit's adoptive brother Henri goes to New York to get Remy for the tithing, and is killed by some assassins who followed him there. Gambit took his brother's body back to New Orleans. Rogue followed him and ended up using her powers against a comatose Bella Donna. Gambit went to Europe to get the Elixir of Longetivity from Candra in order to save Bel's life, and ended up fighting Julien. They all went back to New Orleans, and Gambit discovered just what the Elixir can do: serious damage to the people who take it. Julien is suffering from a side-effect of the elixir, and this discovery angers Gambit, who can't understand why the thieves have risked this for so long. The Tithe Collector shows up and Gambit ends up having to fight both the thieves and assassins. In the end, Jean-Luc tells his son to leave, and Remy did so, after saving Bel's life with the last few drops of the Elixir.
At the start of this issue, Remy is remembering a painful time in his past. He is fifteen years old and accompanying his good friend Etienne Marceaux on his tilling. Etienne ends up being killed when Remy uses his developing mutant powers to try and get them away from the Pig. The scene then moves to present day, where Jean-Luc is telling his son about how he needs Remy's help in protecting a thief from Japan, Zoe Ishihara, and her mutant brother, Shirow, who are being hunted by the Pig. Remy vows that what happened to Etienne will not happen again, and he ends up freeing Zoe and Shirow from the Mengo brothers.
Gambit, Zoe and Shirow have been kidnapped by the Pig. Zoe explains her past to Remy, tells how she was excommunicated from the Tokyo Thieves Guild for disagreeing with her family over Shirow. Meanwhile, in New Orleans, Jean-Luc is beginning to be really frustrated...sick of being the Guild patriarch. In the end, Remy kills the Pig and frees not only himself and the Ishiharas, but also the other kids the Pig had kidnapped.
Professor X has disbanded the X-Men. He gave his reasons, but Gambit doesn't buy them, so he is going to go to Mr. Sinister to see about finding out the truth. He brings his pal Courier with him and together they enlist the aid of Sabretooth, who also needs Sinister's help. They break into Sinister's hideout/laboratory, and are of course attacked by some of Sinister's goons. Ultimately, Sinister agrees to help them on one condition: he wants Sabretooth back.
Jean-Luc LeBeau has been trying to acquire/steal a powerful gem known as the Momentary Princess, for nearly one hundred years. This issue combines the past with the present as this time, Jean-Luc's adopted son Gambit is the one after the gem. We see Jean-Luc, partnered with Sgt. Fury and the Howling Commandos after the gem during WWII, as well as other people who want the gem as well. The funny thing about the gem is, it only appears (how it disappears is beyond me) once every twenty or so years, making it very difficult for anyone to possess it. And yes, at the end of the book, the gem has still escaped being stolen by anyone.
New Sun has taken Remy to his alternate earth, in order to fight with Remy to the death. New Sun is in reality, the Remy of this alternate earth, only he is much more powerful than the Remy we all know and love. New Sun explains the differences between his life and Remy's. They talk for quite awhile, until New Sun announces that he plans on killing Remy. They fight, Remy amazed at just how powerful New Sun is. In the end, Remy figures out that the only way to stop New Sun is to pour every ounce of energy he can into his alternate self. He does this, and New Sun can't contain the energy. New Sun is destroyed, and with the help of his friends Bill and Courier, Remy is saved and brought back to his own world. Remy's powers returned to what they were before, but he's not bothered by that. Nor is he bothered by the fact that he has no idea what's going to happen next.
For the most part, this issue, the final issue in the Gambit series (waaaah), Remy is remembering his days as a young thief-in-training. For some reason I can't really figure out, his adventures all end up around a guy named Mr. Mastiff, the most influential businessman in New Orleans, who really doesn't like Remy at all. In the end, Remy hooks up with Mastiff's daughter, which would probably give the big guy a coronary, but does Remy care? Of course not...and neither does Minnie (the daughter). LOL.
