Hogan slips a top-secret military document into Klink's coat, the better to smuggle the information out of Stalag 13. Unfortunately, Klink attends a party thrown by a suspected German traitor. To save Klink himself from being arrested by the Gestapo, Hogan must find a way to steal the document without anyone being the wiser. Written by Bill Davenport, "The Top Secret Top Cat" made its CBS network debut on March 31, 1967. ~ Hal Erickson, Rovi
