Calvary Gaol, with its grim facade and brutal history, does nothing to improve the connotations of its name. On a chilly night its ghosts can all but be heard chattering, from the doomed political radical to the dapper ladies man with a knife in his sleeve, from the blackmailed doctor to the spiritualist who fed, like a vampire, on the misery of World War I. Calvary is abandoned now, but those ghosts are still calling, and TV producer Chad Ingram can't stop listening. With a crew and a journalist in tow, he resolves to film in the prison's execution chamber.
