He's back! It's been two years since The Midnight Guardian, aided by a mask that enhanced his reflexes and heightened his sensory powers to superhuman levels, brought down criminal sociopath Nicky Diamond in Union City's hour of darkness. Since then, the mysterious figure has faded into the haze of urban legend. But now a sinister regime is threatening all of Europe, and a Nazi scientist and saboteur who calls himself the Sensenmann - supported by a fifth column organizing on the outskirts of town - has set up a secret operation in Union City and pointed a doomsday weapon at the heart of the bustling metropolis. Before long, assistant DA Jack Hunter has no choice but to reassume his avenging alter ego. The world is slowly inching toward war, and it's up to The Midnight Guardian to prevent the first strike by dismantling an enemy from within.
