The year is 1947. As the Cold War starts to warm, the CIA send agents to Argentina on a mission to investigate how the USSR is operating in that South American nation. The group sent is codenamed the Shield Maidens. Accompanying these three experience operatives will be Kay Carr, wife of the Deputy Director, a non-agent but a native Spanish speaker. It is supposed to be a simple assignment - up until the Shield Maidens go rogue.
