Horror starring Keanu Reeves as John Constantine, a man who was born with a gift he didn't want - the ability to clearly recognise the half-breed angels and demons that walk the earth in human skin. Constantine was driven to take his own life to escape the tormenting clarity of his vision, but he failed. Resuscitated against his will, he found himself cast back into the land of the living. Now, marked as an attempted suicide with a temporary lease on life, he patrols the earthly border between heaven and hell, hoping in vain to earn his way to salvation by sending the devil's foot soldiers back to the depths. But Constantine is no saint. Disillusioned by the world around him and at odds with the one beyond, he's a hard-drinking, hard-living bitter hero who scorns the very idea of heroism. When a desperate but skeptical police detective (Rachel Weisz) enlists his help in solving the mysterious death of her beloved 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 otherworldly events, the two become inextricably involved and seek to find their own peace at whatever cost.
