Pôsobia ako ochrancovia utláčaných a mstia sa zlosynom, ako sú zlodeji dobytka a podvodníci. Ich legendárna povesť predchádza ich kroky, ale keď sa jeden z nich ocitne v nebezpečenstve, musia sa spoľahnúť na pomoc nečakaných spojencov, čo vedie k nebezpečným dobrodružstvám a nečakaným spojenectvám.
