The Revenge of the Century

A drunken oath of a patriotic soldier leads to a dangerous mission. A family of four brothers who help him throughout. His confidence and anger guide him to the lands of Great Britain. What exactly does he wish to do. A single man cannot conquer an army. Is he going to steal some intelligence but his own country would not co-operate with him? What is he going to do single-handedly? He is going to steal but not any intelligence nor is he going to raid royal treasure. Even if he succeeds in exacting the revenge. Will he be able to go unscathed or will he pay the price?
