Captain Solomon Kane is a brutally efficient 16th century killing machine. When Kane decides to attack a mysterious nearby castle to plunder its rumored riches, his men are picked off by demonic creatures until he alone is left to face the Devil's own Reaper, dispatched from the depths of Hell to lay claim to his hopelessly corrupt soul. Though Kane manages to escape, he knows that he now must redeem himself by renouncing violence and devoting himself wholly to a life of peace and purity.
