When Brock and Dr. Venture are kidnapped from the funeral of a college friend, the boys enlist the aid of the original Team Venture: a group of superscience adventurers who worked for their grandfather in the sixties.
Dr. Venture, in a bid to make some much-needed money, opens up the compound as "Rusty's Day Camp for Boy Adventurers." But while the children are kept busy with activities like judo lessons from Brock and quizzing with Master Billy Quizboy, the Monarch sends in the Murderous Moppets to spy on his former arch-nemesis.
Love is in the air, kind of, when Dr. Venture encounters his childhood friend, Dr. Tara Quymn, in the Amazon Rain Forest. But while Rusty puts the moves on his old play date, Hank makes a play for Dr. Quymn's twin daughters, Nancy and Drew, who in turn, only have eyes for Dean. And the Quymn's bodyguard, Ginnie, is hot for Brock. Maybe. But all of their romantic interludes will have to be put aside when the terror of the Wereodile threatens their camp.
All basements are kinda spooky, but the Ventures are about to learn the hard way that beneath the foundations of the Venture Compound lie deep, dark secrets... great and small. Only the one-two punch of magic and technology can save Doc, Brock--and perhaps the planet--from certain doom as the boys recruit The Order of the Triad and Pete White to get to the bottom of a thirty year old mystery.
Bored and under-whelmed with his new Guild-assigned arch-enemies, The Monarch seeks to re-spark his old hatred by secretly visiting the Venture Compound while Dr. Venture is away at the Science Now conference. His passion for arching all things Venture may threaten to seriously cool things with his other love, Dr. Mrs. The Monarch, but does it really count as arching when there's nobody home? Or is there?
Determined to honor the father he never knew, Jonas, Jr. converts Spider Skull Island into a Team Venture Museum. Unfortunately, he invited all of his father's surviving friends and enemies to the grand opening.
There's nothing like a party to stir up decades worth of sibling rivalries, bitter regrets and half-forgotten hatreds.
