The boys are lost in the woods somewhere in Scotland, where they accidentally find an old plane wreck, and in the dead pilot's hands, an envelope containing the innovative formula of a low-cost, high-grade synthetic fuel as well as a note with the clear direction to burn inventor Brian Wilk's notations. Under Judge Fulton's directions, Brett and Danny will try to keep out of sight this monumental discovery, but before long, all interested parties, including significant oil tycoons and a parade of women all asserting to be the deceased's only daughter, will attempt to claim the formula. With the scientist's accident being indeed a murder, the Persuaders are determined to see justice done, and in the process, find out if the world is really ready for the formula.
