The gates to Hell are open and something beckons... The last of Earth's magicians are living in fear. A Cenobite Hell Priest known as Pinhead is killing them off, gorging on their knowledge to enhance his own magical powers as part of a quest to takeover Hell. Meanwhile, Private Investigator Harry D'Amour is fulfilling the final wishes of the dead, who communicate with his business associate, the blind medium Norma Paine. But while investigating one such case, Harry inadvertently opens up a rift between hell and the real world. When nemesis Pinhead emerges through the portal, a vicious battle ensues. After failing to enlist Harry as one of his Scarlet Gospels, an elite group of indefatigable messengers who will witness his takeover of hell, Pinhead captures Norma and Harry realizes he must go through hell - literally - to save her.
