The magnificent Martin fires on the hills around Ahrweiler have not yet died down when a body is found during the ice wine harvest at the Calvarienberg Monastery: Julius Eichendorff's fiercest competitor - frozen solid in a block of ice. Quickly, the head of the Alte Eiche falls under suspicion of murder. To make matters worse, he cannot remember anything from the night of the crime due to a severe drunken blackout. Julius desperately tries to prove his innocence, but his chances are worse than that of an ice cube in hell.
