Synopsis by Hal Erickson
Two of the three scientists working on a cobalt bomb have been kidnapped by enemy agent Eric Stavak (Albert Paulsen), who has hidden his captives somewhere in San Francisco. The IMF must protect remaining scientist Dr Robert Webster, who holds the equations for the deadly weapon. Posing as Webster, Phelps pretends to fall into a trap engineered by Stavak--while Barney prepares to simulate a devastating earthquake. Written by William Read Woodfield and Allan Balter, "The Survivors" first aired on September 24, 1967.
