The CSI team is called in after four monks are shot to death at close range while worshipping in a Buddhist temple. As Grissom (William L. Petersen) looks into this possible hate crime -- and also advises Sara (Jorja Fox) to be more respectful of the dead than usual -- Catherine (Marg Helgenberger) dolefully reopens a homicide case in which her best friend was killed. It seems that the man convicted of the crime has sworn on his deathbed, and before the cameras of a TV news program, that he is innocent. ~ Hal Erickson, Rovi
