Well, there's this: https://www.truetvmovies.net/store/p435/The_Long_Island_Incident_%28TV_1998%29_Laurie_Metcalf%2C_Mac... which I found by Google search of "Long Island Incident (1998)", select Video among the options under the search box, and looked at the first video. Although it was only 14 min long, it had a link to this vendor, where I had to search for the title again. I don't know anything about this vendor; proceed with caution. When I searched for reviews of the vendor, it was easy to find complaints.
I don't see any free versions out there. You might try eBay or iOffer to see if anyone has a used copy to sell cheaper than this. If not today, save the search and get notifications from eBay when one is posted, if ever. On iOffer you can post a want ad.
