A haunted castle and a ruined bloodline.
Manfred, wicked lord of Otranto Castle, is horrified when his son is crushed to death on his wedding day. But rather than witness the end of his line, as foretold in a curse, he resolves to send his own wife to a convent and marry the intended bride himself.
However, Manfred's lustful greed will be disturbed by the terrifying omens that now haunt his castle: bleeding statues, skeletal ghouls and a giant sword – as well as the arrival of the rightful prince of Otranto . . .
