The Man from U.N.C.L.E. 1x12

When a minor European leader is assassinated, Solo steals a medallion from his body containing a microdot listing the THRUSH agents in the country, but must elude the secret police and outwit intelligence agent Satine (Ricardo Montalban), who also wants the medal. Teacher and tour guide Sara Taub (June Lockhart) and her high school students are used by Solo to try and sneak the medal over the border.
