The case of a missing boy, with a suspected emergence of mutant powers and connection to the Hellfire Club, has drawn the attention of both the X-Men and the WILDC.A.T.S.
It was while watching the Cameron estate, home of a member of the Hellfire Club, where Nightcrawler came face to face with one of the WILDC.A.T.S., who was also tracking “daemon” activity.
Two months later, when the Cameron estate is throwing a gathering, the X-Men seize the chance to plan a stealth attack with a team comprising of Cyclops, Phoenix Wolverine and Nightcrawler.
Meanwhile, Marlowe, part of the WILDC.A.T.S., has been invited to the gathering. He brings with him a couple of members of the team as backup.
Cyclops sends Wolverine and Nightcrawler to infiltrate the estate. Along the way, they meet with a couple of WILDC.A.T.S., among them one that confronted Nightcrawler two months ago.
After an elaborate dinner in period costume, the Hellfire Club retire for the night to partake in extravagant sexual pleasures. The visiting WILDC.A.T.S. are quickly apprehended by the Hellfire Club and taken prisoners, to be part of the “summoning”, which requires a “virgin”, hence the kidnapped boy, and an “immortal”, referring to Marlowe.
The X-Men and the rest of the WILDC.A.T.S. attack just as Cameron summons the devil. The defeat of the devil causes the entire estate to go up in an explosion. Fortunately, Phoenix was able to save everyone, including the Hellfire Club.
The X-Men and WILDC.A.T.S. part ways once again, sensing darker days ahead.
