In Victorian Britain, secret agents Sidney Orebar, Moira Hunter, and Liza Hart are assigned to investigate a series of deadly railway “accidents.” As they uncover a pattern of sabotage, they trace the crimes to a powerful industrialist secretly orchestrating disasters to weaken the nation for profit and influence. Framed for the attacks themselves, the trio must evade arrest and gather proof while racing to stop a final act of destruction. At the critical moment, Benjamin Disraeli intervenes, revealing the truth, clearing their names, and presenting the evidence that brings the traitor to justice—ensuring the safety of the country and the quiet triumph of its unseen defenders.
