Key Witness
An average Los Angeles citizen witnesses a gang murder when he stops to use a telephone. Aware that he is the only witness against them, the gang members seek out his identity and terrorize him and his family to keep him from testifying against them. Only by psychologically playing one gang member against the others is the man able to bring the police to his rescue.
