Plot: John Constantine (Reeves) fights a battle most humans are totally unaware of. He knows that Heaven and Hell are waging a battle - he is able to see behind the normal, and sees the combatants hiding behind their falseness - and they see him. Now, he’s dying - but before he finally goes, he must help a woman (Weisz) who may, unknowingly, be at the center of an evil attempt to take over the world. Based on the DC Comics/Vertigo Hellblazer graphic novels.
