Hoping that the instructions can save her people and restore freedom, Lady Catherine Wilhelm, a janitor in custody of the stolen instructions races home in a cargo ship. However, the ship is pursued by a warship. Wilhelm escapes onto an airlifter, which turns out to also have been damaged and entered by Shock Soldiers, and she is incapacitated by one with a prod. After discovering Catherine's letter, Shish persuades him to come with him to the Caribbean. While connected to the Morum Network on the ISS, R discovers Wilhelm is aboard the station. Bill's plan works flawlessly in that they are fast in subduing the officers and guards in the damsel's cellblock. Unfortunately, nobody thought to plan for their escape, and Catherine takes charge, blasting a pit in a grate and jumping through while Anthony and Bill hold off a troop of Shock Soldiers. Chuks, Bill and Anthony all dive after the mistress into the unknown. The only remaining ships (those of Bill and Anthony) return to Tikal and a victory celebration commences, complete with medals for the heroes, Anthony Took and Bill Gunther, presented by Catherine Wilhelm.
