Two sexy female detectives are kidnapped one by one. The first one is grabbed and pulled into a dark alley.
The second Asian detective is lured into a warehouse by a suspicious looking man. She is quickly chloroformed and tied up.
The two detectives wake up tape gagged.
Later (after some cutting out some inappropriate scenes), the two are chloroformed to sleep again.

Edit: Wow, this is one popular scene! The original source is: http://g.e-hentai.org/g/208473/d83b8551c1/ - WARNING, contains nudity.
