The crash of a private jet exposes a heroin-smuggling operation based in Mexico. The Angels head south of the border -- Kelly (Jaclyn Smith) posing as a vacationing schoolteacher, Jill (Farrah Fawcett-Majors) as a swimming instructor, Sabrina (Kate Jackson) as a stewardess -- to get the goods on the smugglers. Their main target is a drug kingpin known as Escobar, whom no one has ever seen, and thus could be any one of the episode's main characters (except, of course, the Angels). ~ Hal Erickson, Rovi
