Trusty Eckart and Tannenhäuser

The Trusty Eckart is a mediaeval prince living in the security of his castle, or so he thinks. But he is alarmed when he hears that his nemesis, the Duke of Burgundy is riding towards him, having already killed Eckart's son whom he had previously imprisoned. And the Duke's visit will yield even more tragedy for the prince. But Eckart's death will not end the vicious cycle of death that follows anyone who receives a kiss from the dreaded ghost referred to as the "Emmissary of the Hill".
