Despite being relentlessly pursued by Pinkerton detectives and an assortment of hired killers, Connor Mack and his twin sister, Abby, are determined to see things through with their mentor, gunslinger River Hicks. The quest to clear Hicks of a false murder charge requires them to find and confront the rich, powerful foe who seems bent on destroying them. Their journey takes an unexpected turn after they're involved in a bloody confrontation between a bounty hunter and a group of vicious outlaws. Ultimately, this leads them to the town of Land's End where a strange set of circumstances embroil them in a heavyweight boxing match, a high-stakes poker tournament, and much more. Unbeknownst to Connor and Abby, their three malevolent brothers have also been recruited to work against them. All roads lead to Land's End for a showdown that will take place not only in the boxing ring and the gaming tables, but in the dusty street as well. Connor, Abby, and Hicks have no choice but to play the hand they're dealt in this ongoing killer's gamble...and it's certain that treachery, betrayal, and death are in the cards.
