Woman lost at sea off Darwin, sharks – Discovery Channel. Where can I find it?
The segment, which was part of Discovery Channel’s “Shark Week” a few years ago (2004, I believe), is called “Primal Scream.” I bought it as a single DVD back then and watched it again just recently. You can buy it from the Discovery Channel’s website as part of their “Ultimate Shark DVD Set” (not too pricey at $30). The website’s description of the DVD could be better, but it’s the video you described above. I don’t know whether you saw an edited version, but the total program length is about 37 minutes.
