Scorchy [1976] [DVD]

Connie Stevens is a pert, buxom Hollywood B-grade starlet, custom built for the exploitation genres. She plays a 'Police Woman' type undercover agent trying to crack a narcotics ring operating between Rome and California. Known for her promiscuous behaviour and unconventional tactics, she's highly effective although often castigated for her entrapments.

Embedded, she's recruited by a drug dealer's wife to act as courier for a cartel, but things go awry. She's on her way to solving the mystery when she seduces the drug dealer's young brother-in-law for information - alas, he expires before he can 'give it to her'. And so begins a sordid path of lurid seduction and retributions. ~ imdb
