Schultz accidentally catches Gestapo major Kriegel (Gavin McLeod) in an illegal cash transaction. To cover his own behind, Kriegel orders Schultz to the Russian front. Hogan and his men must simultaneously expose Kriegel and rescue Schultz. "Clearance Sale at the Black Market" was written by Laurence Marks. ~ Hal Erickson, Rovi
