Aboard their train "The Wanderer", West and Gordon examine the severed head of decapitated scientist Thaddeus Morton, finding a clue that leads them to Arliss Loveless, a legless ex-Confederate officer who also happens to be an engineering genius. Infiltrating Loveless's plantation during a party, the duo rescues a woman named Rita Escobar. She asks for their help in rescuing her father, Guillermo Escobar, one of the kidnapped scientists. Loveless holds a demonstration of his newest weapon, a steam-powered tank, and angers McGrath by using his soldiers for target practice. Accusing McGrath of betrayal for surrendering at Appomattox Court House, Loveless shoots him and leaves him for dead. Gordon, West, and Rita find the dying McGrath, who reveals he was framed by Loveless for the massacre of New Liberty, where West's parents died. The three catch up with Loveless on "The Wanderer". After a brief fight, Rita accidentally releases sleeping gas, which knocks out West, Gordon, and herself.
