The Last Mystery

S01 E07 • Tuesday, Nov 14, 1961 • Nov 14

It is 1972 and the message from the Andromeda Nebula has stopped transmitting. Fleming has been able to determine the correct formula to counteract the effects of the enzyme and save Dawnay. Fleming, Dawnay, Reinhart, and Judy now agree that Andromeda must be stopped - however, the military now has control over the project. Andromeda tries to kill Fleming but fails; she confesses to Fleming that she is a slave of the computer, which is working to take over humanity. Fleming takes an axe to the machine, destroying it. Now free of the machine, Andromeda is able to burn the instructions for building the computer so that the machine cannot be rebuilt. She flees with Fleming to one of the islands near the base. Pursued by soldiers, they hide in a series of caves on the island. However, Andromeda is apparently killed when she falls into a deep pool. The dejected Fleming is brought back to Thorness by the soldiers.
