An underground data-storage facility uncovers a problem when they excavate a tunnel for a new wing. Carl investigates the deaths of several employees of the facility who appeared to have been killed by a wild animal, and he discovers a rampaging reptile that has been disturbed by the digging of the tunnel. As Kolchak tries to stay one step ahead of the law, the beast continues its assault on the facility, destroying anything and everything in its quest for the eggs that have been stolen from its nest.

Final Coda Of Carl
10 November 2014 | by (North America) – See all my reviews

Last episode of this sadly brief series sees Carl Kolchak(Darren McGavin) going underground at a state-of-the-art data storage facility where several employees were killed by what turns out to be a humanoid reptilian creature that was disturbed when construction of a new wing threatened its nesting place, and indeed eggs were stolen. Despite zero cooperation, Carl goes to outrageous lengths to repeatedly bluff and then smuggle his way in, fleeing from both angry officials and the creature itself... Good guest turns by Kathie Brown(McGavin's wife) and Tom Bosley help this unpopular episode, though I enjoyed it all the same, as the creature(while overexposed) is still menacing, and the last scene of an escaping Carl is a fitting coda for this character, sadly the last time he would ever be seen.
