Mr. Waverly predicts trouble when his top British U.N.C.L.E. agent Brian Morton (Peter Bromilow) becomes engaged to "civilian" Laura Adams (Diana Van der Vlis). Sure enough, both Morton and Laura are kidnapped by T.H.R.U.S.H. operative Commander Kroler (Alfred Ryder), who uses Laura as a bargaining chip to force Morton to turn over the plans of U.N.C.L.E.'s new super-submarine. Written by Leonard Stadd, "The Deep Six Affair" first aired on December 25, 1967. ~ Hal Erickson, All Movie Guide
