Gina "Gold Digger" Diggers is still on the go all over the world and beyond in search of old treasure and new knowledge. She briefly loses a valuable artifact to Ryan Tabbot, a cute (but self-centered) competitor, in Istanbul, but trails him soon enough to an ancient underground spaceport in Egypt. Ryan then joins her, arch-rival Penny, and friend/transport man Ace on a trip to the Bermuda Triangle, where an anomaly leads them into chronospace and onto the trail of a time-traveling genius dog and his pet boy. But if they don't bring this mutt mastermind to heel, he'll change history to ensure a future where Caninekind rules over Man!
