The film is about a radio shock jock who tries to find redemption by helping a man whose life he inadvertently shattered.PlotJack Lucas, a selfish, misanthropic shock jock, becomes suicidally despondent after his insensitive on-air comments inadvertently prompt an unstable caller to commit a mass murder-suicide at a popular Manhattan restaurant. Three years later, Jack is working with his girlfriend Anne in a video store in a mostly drunken, depressed state. One night while on a bender, he attempts suicide. Before he can do so, he is mistaken for a homeless person and is attacked and nearly set on fire by thugs. He is rescued by Perry, a deluded homeless man who is on a mission to find the Holy Grail, and tries to convince Jack to help him. Jack is initially reluctant, but comes to feel responsible for Parry when he learns that the man's condition is a result of witnessing his wife's horrific murder at the hands of Jack's psychotic caller. Perry is also continually haunted by a hallucinatory red knight, who terrifies him.
