Constantine (2005)

Born with a gift he didn't want, the ability to clearly recognize the half-breed angels and demons that walk the earth in human skin, Constantine (Reeves) 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.
