Plato, the most advanced computer in the world, which could be used to target intercepting missiles, keeps breaking down. The body of a professor on the team is found within: very cold and very dead.

All of the information on this episode so far has been user-submitted. This episode has not been released on video in North America yet, so I have not been able to view it.

The boom mike is seen, immediately after Dr. Kearns shouts "All right, roll 'em!". It reappears just after Steed has disarmed Clarice and Broster in Cathy's kitchen.

Cathy has to restart her dialogue when Broster cuts her off by asking "What are you doing...?"

A scraping sound is accompanied by a bump of the camera when Dr. Kearns is speculating how he would murder Dr. Clemens.

Steed: (to Cathy) "I've just dropped by to bring Sheba in for you. Will you look after me? Quarantine, you know." (Should'be been "Will you look after her?")
