A former Canadian agent (David) relegated to the Filing and Records Department accidentally meets a former British agent (Val) with whom he frequently collaborated in the "old days". He is approached by a defecting Soviet agent with secrets to sell and asks Val's assistance in verifying the story. Brian Linehan, making his television acting debut, is Graydon, David's tough chief who has little use or respect for David and his generation of agents, preferring to use the highly computerized technology at his disposal.
