The Fisher King

Jack Lucas, a narcissistic, misanthropic shock jock, becomes suicidal and despondent after his insensitive on-air comments inadvertently prompt an unstable caller to commit a mass murder-suicide at a Manhattan restaurant. Three years later, Jack is working for his girlfriend Anne in a video store in a mostly drunken, depressed state.

One night, while on a bender, he contemplates suicide. However, he is attacked and nearly set on fire by thugs who mistake him for a homeless person. He is rescued by Parry, a deluded homeless man who claims his mission is to find the Holy Grail.
