Batman is back to fighting crime in Gotham, now cracking down on Black Mask and gang. He blocks Black Mask's shipments of drugs in the harbor and locks up a lot of his men. Bruce is happy with the results but is still haunted by the guilt over his previous Robin, Jason's death. Meanwhile the criminals are being hunted down by a guy called Red Hood, working for Black Mask as security and assassin. Batman confronts him but he escapes. Batman notices that he is very well knowledgeable about Batman's tactics and methods and is openly challenging them. Red Hood soon becomes increasingly unstable and turns against Black Mask and gang. Batman goes on to investigate the new violent vigilante who might have connections to his own dark past.
