Based on the DC/Vertigo comic book Hellblazer and written by Kevin
Brodbin, Mark Bomback and Frank Capello, Constantine tells the story of
irreverent supernatural detective John Constantine (Keanu Reeves), who has
literally been to hell and back. When Constantine teams up with skeptical
policewoman Angela Dodson (Rachel Weisz) to solve the mysterious suicide
of her twin sister (also played by Weisz), their investigation takes them
through the world of demons and angels that exists just beneath the
landscape of contemporary Los Angeles. Caught in a catastrophic series of
otherworldy events, the two become inextricably involved and seek to find
their own peace at whatever cost.
