The Haunted Castle portrays vicissitudes of a noble family inhabiting an ancient castle, struggling throughout long years with reverses of fortune, because of a cruel curse cast on the entire line. Visits of the vindictive ancestors’ spectres seeking redress for the old-time wrongs, the past unsettled conflicts, disclose grim secrets of the mansion’s former proprietors. Chance discovery of the 17th century diary reveals the reasons for casting the curse on the dynasty’s posterior generations.
