Synopsis by Hal Erickson
A microfilmed list of undercover narcotics agents has been stolen and divided into two halves, with each half in the possession of a different drug kingpin. Though bitter enemies, Ramon (Fernando Lamas) and Arturo Sandoval (Percy Rodriguez) are poised to forget their differences so that the microfilm can be reassembled. To prevent this truce and recover the film, the IMF cooks up an elaborate ruse involving a stamp collection, a cache of rare coins, and a specially trained terrier named Chico. Originally telecast on January 25, 1970, "Chico" was written by Ken Pettus.
