Prisoners are being beaten to death at El Toro Prison. Guard Larry Clark plans to go to the authorities, but before he can talk, a bomb rips through his house, killing him and his wife.

Determined to crack the case, August goes undercover in the prison, but his cover could be blown when it's learned that Robert Hatcher, his former partner, is being transfered to the prison.
