Once upon a time, when T.V. was in black and white and there were only three channels, there lived Bax and Beverly Bagley, who were twins. They had an ordinary, slightly dull, picket-fence life. Most of their time was spent being carefree and goofing off with their friends. But sometimes, they worried about growing up, and if that meant they would become boring just like their parents.

But one day, their Aunt Lantis - their relative who was a very snappy dresser, was shockingly beautiful, had the air of exotic adventures and vast possibilities that they had never actually met - showed up unexpectedly and in a car of her own design. Poignant and thrilling events unfold as the twins and Aunt Lantis try to save her fiancé, the 12th Earl of Loch Ness, find Nessie, stop the mysterious villain who has orchestrated this undersea apocalypse, and return home before Mother and Father Bagley become alarmed.
