Meanwhile, a former SS general previously in command of Nazi special projects, Hans Kammler, has been spotted in Argentina by an American agent-who is then promptly murdered along with every member of the local CIA network. The task of locating a potential secret Nazi base then falls to Buck, his friends? and the Sea Dart.

That leaves Buck and Mossad agent Beata to continue the search, both for their friends and for the secret Nazi base. A mission that is becoming more urgent by the hour, as this remnant of the Third Reich managed to escape with some of their secret weapons at the end of the war, and are preparing for a major operation.
