A figure from Dr. Venture's past haunts him during his annual vacation to Spanikos.

Space. The final frontier, where no one can hear you scream, revenge is only served cold, and the drinks are comped in the casino. Join the Ventures–and pretty much everyone they’ve ever crossed paths with–as they rocket to the Gargantua-2 space station for an epic, hour-long adventure that will change the Ventureverse as we know it forever.

Doc uncovers a mysterious invention that could make or break Dean's college aspirations and The Monarch makes a bad first impression on Dr. Mrs. The Monarch's co-workers.

The Venture headquarters is either possessed, just regular haunted, or suffering from a computer glitch; Dr. Orpheus and the Order of the Triad are called upon to unlock the mystery.
