Colonel White leaves Cloudbase after the Mysterons threaten to kill him, reasoning that such a threat endangers the other members of Spectrum. He takes refuge on board a submarine and is assigned protection in the form of Ensign Soames. However, neither the crew nor the Colonel realize that Soames is a Mysteron agent. With the Mysterons seemingly free to carry out their threat, could this be the end for Colonel White?
