在一场冠军杯足球赛中,一个狙击手让观众席瞬间大乱。这部影片获得金奖提名,在70年代成为记录社会颂扬暴力的代表之作。A psychotic sniper plans a massive killing spree in a Los Angeles football stadium during a major championship game. The police, led by Captain Peter Holly (Charlton Heston) and SWAT commander Sergeant Button (John Cassavetes), learn of the plot and rush to the scene. Still, they may be too late, as an all-star cast finds itself lined up in the sights of a gun-toting madman.
