Houdini and Spawn attend a conference that has been taken hostage by a madman with an atomic bomb. As Houdini watches the bomb's countdown, he realizes that he's been double-crossed -- the original plan was to destroy Spawn in the blast, but Houdini is being sacrificed as well. At the last minute Houdini channels the explosion into another reality.
