This episode takes place during Christmastime in Chicago. Vincenzo is preparing to take his first vacation in five years: an assignment on the final voyage of the cruise ship Hanover. Unfortunately, auditors choose this time to review the INS books. So, Kolchak is sent in his place. Once aboard, Carl has to interview people about the practices of singles aboard ships like this. One of the passengers is a strange antisocial military man with a bite on his arm. What Kolchak dosen't count on is the appearance of a man-animal creature that attacks people and disappears. It is never said if these people are dead or alive. Kolchak uses his own brand of investigation and comes to the realization that there is a werewolf on board. Naturally, the captain of the ship dosen't completely believe him, but he must have some reservations when he tries to outrun the rising moon to shore. With the help of some of the passengers and crew, Kolchak has to make some silver bullets so he can kill the werewolf. At the end, we never find out if the werewolf died or not, but he was obviously wounded by the bullets. There is also some traces of government cover-up involving NATO. This was a pretty decent episode. This is also the second Kolchak episode that took place mostly outside Chicago. I also find it hard to believe when Kolchak says there is no record of any wolf attacks on this continent.
