London, England 1869. On learning about the death of his much-loved father, Captain Austin Willems of the 67th South Hampshire Regiment of Foot returns home to discover his father was swindled by a railway company he heavily invested in. Austin learns that the ruthless directors of Grand Overland Rail hide behind privilege and peerage to prey on their unsuspecting victims and that their greed contributed to his father's ailing health and eventual death. With no other option, Captain Willems decides revenge is his only recourse.
Taking matters into his own hands, Captain Willems embarks on a daring plot of vengeance; however, when people begin dying, he quickly grasps that Grand Overland Rail director's influence is far-reaching and they'll stop at nothing, including murder, to ensure their honour and reputations prevail. With the support of retired sergeant, Oliver 'Ollie' Nagle and the beautiful Harriet Stephenson at his side, he is in danger of losing everything. Even with the Metropolitan Police at his heels, will Austin restore his father's legacy, stay alive and remain out of jail?
